WinRAR puts you ahead of the crowd when it comes to compression. By consistently creating smaller archives, WinRAR is often faster than the competition. This will save you disc space, transmission costs AND valuable working time as well.

Features:

• WinRAR supports all popular compression formats (RAR, ZIP, CAB, ARJ, LZH, ACE, TAR, GZip, UUE, ISO, BZIP2, Z and 7-Zip).
• WinRAR is ideal for multimedia files. WinRAR automatically recognizes and selects the best compression method. The special compression algorithm compresses multimedia files, executables and object libraries particularly well.
• WinRAR allows you to split archives into separate volumes easily, making it possible to save them on several disks for example.
• WinRAR is also ideal, if you are sending data through the web. Its 128 bit password encryption and its authenticated signature technology will give you the peace of mind you have been looking for.
• WinRAR is shareware, meaning you have the chance to thoroughly test it. The program can be used absolutely free of charge for 40 days!
• WinRAR licenses are valid for all available language and platform versions. If you have purchased several licenses, you can even mix versions to meet your own personal needs.
• WinRAR gives you all future UPDATES for FREE!

What's New:

• Added download link for Beta version 5.9.1
• 'Preserve source files last access time' option on 'Time' page of archiving dialog permits to preserve the original last access time of archiving files.
• Command line -tsp switch can be used to preserve the original last access time of archiving files. It can be combined with other -ts switches, like: rar a -tsc -tsp arcname files
• It is allowed to combine several modifiers in the same -ts switch. For example, we can use -tscap instead -tsc -tsa -tsp.
• WinRAR can read default values of command line switches from rar.ini text file, which can be stored either in the same folder as WinRAR.exe or in %APPDATA%WinRAR folder. This file includes strings in following format: switches= switches_ = First applies switches to all and second to individual commands. For example: switches=-m5 -s switches_x=-o+ Most of switches specified in rar.ini are used only in the command line mode. Some switches can be applicable both in shell and in command line modes. Previously this rar.ini format was supported only by console RAR.
• Command line -agf switch specifies the default format string for -ag switch. It has a practical value only if placed to rar.ini configuration file or to RAR environment variable. For example, if we set RAR environment variable to -agfYYYY-MMM-DD, we can use -ag without a parameter with YYYY-MMM-DD format string assumed.
• Switches -ed and -e+d can be used in archive processing commands for any combination of RAR and archive operating systems. In older versions RAR for Windows could not use them for Unix RAR archives also as RAR for Unix for Windows RAR archives.
• Previously 'Test' command failed to check integrity of archived NTFS alternate data streams and issued 'Unknown data header format' warning if size of such stream exceeded 16 MB. This limitation is removed now.
• Archiving speed for large NTFS alternate data streams on multi-core CPUs is increased.
• 'Find' command:
  • when extracting encrypted files directly from 'Search results' dialog, password prompt was issued for every found file even if all files belonged to same archive. Now password is requested only once per archive
  • Ctrl+A hotkey selects all files in 'Search results'.
• Archive comment window:
  • previous versions did not allow to use Ctrl+W shortcut to close WinRAR when comment window had keyboard focus. Now Ctrl+W works also from comment window
  • mouse wheel is supported also for comments with ANSI Escape sequences
  • for some lenghty comments with ANSI Escape sequences last line of comment was visible only partially even after scrolling up to bottom. It is displayed comletely now.
• Maximum path length for files in 7z archives is increased up to 2048 characters. While such lengthy paths were already supported for RAR and ZIP formats, previous versions limited the path length to 260 characters for 7z archives.
• If archive or file name is too lengthy to fit to archiving or extraction progress window, it is truncated. Previously such names were truncated at the end, making the file extension invisible. This version truncates them removing the path component and symbols in the middle, but preserving beginning of file name and file extension.
• If files selected for archiving differ only by extension, a proposed archive name is based on their name part. For example, archiving dialog will propose Readme.rar if we selected Readme.txt and Readme.doc. Previous versions always generated the archive name based on parent folder name for several selected files.
• 'Symlink' and 'Hardlink' is diplayed in 'Type' column for symlink and hardlink records in .tar archives. Previous versions displayed a proper type for such records only in .rar archives.
• Copying and pasting files from large archives could fail if extraction took a lot of time. This version can paste files from such archives as well, but we have to start extraction already on 'Copy' command and not on 'Paste' to achieve this.
• Similarly to RAR5 volumes, recovery volumes in RAR4 format use the same width of volume number field as corresponding RAR volumes. While previously WinRAR could create arc.part01.rar and arc.part1.rev in RAR4 format, now both types of volumes will use 'part01'.
• 'Set font..' button in 'Settings/File list' also changes the folder tree panel font. Previously it changed only the file list font.
• 'Find files' and command line mode 'i' commands:
  • if 'Use all tables' option or 't' modifer of 'i' command are used, additionally to already supported ANSI, OEM and UTF-16 encodings WinRAR will search the specified string in UTF-8 files as well
  • better support for Unicode text strings
  • better performance, especially for case insensitive search
  • hexadecimal search output includes both text and hexadecimal representation of found matches.
• File and total progress bar is displayed when unpacking tar.bz2, tar.gz, tar.lz, tar.xz, tar.z archives. Previously only the total progress was displayed properly for tar.bz2, tar.gz and tar.z. Neither file nor total progress was displayed for tar.lz and tar.xz.
• 'File list/Files/Exact sizes' option also changes the file size format in WinRAR status bar.

Bugs fixed:

• if non-existent path is specified in archive name in archiving dialog, WinRAR proposes to create such path. Previous versions could create such path in WinRAR start-up folder instead of currently displayed folder
• WinRAR could crash when adding the recovery record in RAR5 format on CPUs not supporting CPUID EAX=7 command and returning random data in response. These are some CPUs from early 2000s
• WinRAR failed to create archives after dragging files with right mouse button in Windows shell, dropping them to another folder, selecting 'Add to archive..' in context menu and enabling 'Put each file to separate archive' option
• 'winrar r *.zip' command repaired only the first ZIP archive in the set if all archives had numeric names like 1.zip, 2.zip and signatures in the beginning of archives were missing
• previous WinRAR version failed to unpack folder records in archives created by RAR 1.50
• in rare cases WinRAR failed to extract and reported an error for valid .gz archives produced by some compression optimization tools
• progress bar in tray icon never reached 100% in high DPI mode
• creation and last access time was not displayed for archived folders if folder records were stored in archive after folder contents
• 'Skip encrypted archives' option in 'Convert archives' command did not work for 7-Zip archives with headers encryption.

What's New in 5.9.1 Beta:

• RAR compression speed is improved for CPUs with 16 and more cores
• 'Fastest' method (-m1 command line equivalent) typically achieves a higher compression ratio for highly compressible data types when creating RAR5 archives.
• Maximum number of utilized threads is increased from 32 to 64. Command line -mt switch accepts values from 1 to 64.
• 'Multithreading' parameter on 'General' page of WinRAR settings is replaced with 'Threads' input field, where you can specify the desired number of CPU threads. It can take values from 1 to maximum number of available logical CPU units.
• WinRAR displays packed and unpacked folder sizes when browsing archive contents.
• 'Total folders' field is added to list of archive parameters displayed by WinRAR 'Info' command. Same field is added to 'Archive' page in archive properties in Windows Explorer.
• Window including a progress bar and 'Cancel' button is displayed if reading archive contents takes noticeable time. It can be useful for archive formats with slower access to contents, such as large TAR based archives like .tar.gz and tar.bz2.
• Archiving and extraction progress windows, also as progress windows for some other commands, can be resized.
• 'Repair' performance for RAR5 archives with recovery record and without data shifts is improved. It deteriorated in WinRAR 5.80 and is now restored to original level.
• Password prompt is not issued when performing recovery record based repair for RAR5 archives with encrypted file names. This command can be performed without providing a password.
• If folder for converted archives in 'Convert archives' command does not exist, WinRAR attempts to create it. Previous versions failed to create converted archives in non-existent destination folder.

Bugs fixed:

• 'Repair' command could erroneously display 'Recovery record is corrupt' message when processing an archive with valid recovery record. This message did not prevent further repair operation
• if quick open information option was set to 'Do not add' in default compression profile and this profile was loaded by some command or dialog, WinRAR ignored quick open information when browsing contents of RAR archives. For example, it happened after opening archiving or password dialogs
• Ctrl+C 'Copy' shortcut key did not work in archive comment window
• if 'Put each file to separate archive' and 'Archives in subfolders' options were set, WinRAR ignored the destination path specified in archive name field.

When was the last time you update your R and RStudio?

I installed RStudio and R a year ago, and never update it since then. Today I just noticed I cannot install new R packages because of my old R version. So I explore some ways to update R and would like to share with someone who is also looking to update R on RStudio.

The problem

RStudio and R cannot update on their own because some packages may not work after switching to the new version (You can still downgrade R version in RStudio if something went wrong though). After you install the new version, the previously installed packages will not go to next version. So it is required extra procedures to move the packages.

Here are 3 ways you can update R version in RStudio. Note that we need to move the install R packages, which I will show how at the end.

3 Solutions to update R on RStudio

Solution 1) Manually install (Recommended if you don't care about the old packages)

The first method is to download a new version of R from R website > CRAN. Then restart your RStudio. The new R version will be loaded automatically.

The new R version appear right after I install R and restart RStudio

Update 29/05/2019: For Mac users, solution 3 is too painful and not working well for me. This method is fast and working well. I would recommend to save your time from headache and use this method. Take note of your previous packages so you can install them again as needed.

Solution 2) Windows only – use installr

installr is the R package which helps install and update software.

The R code you will need for updating R is: (credit goes to Cara Wogsland for the code)

install.packages('installr')

library(installr)

updateR()

You can find the tutorial on how to use installr to update RStudio on R-Statistics website.

Solution 3) Mac only – use updateR

Similar to installr, updateR is the package to help updating R on Mac OS.

The R code you will need is these 5 lines: (credit goes to jroberayalas for the code)

install.packages('devtools') #assuming it is not already installed

library(devtools)

install_github('andreacirilloac/updateR')

library(updateR)

updateR(admin_password = 'Admin user password')

You can find in-depth tutorial on how to use updateR package on this blog.

How to move the previously installed R packages

This is the instructions for Mac OS user (who used solution 1 or 3 above). For Windows user, installr package will do this for you

(credit goes to RyanStochastic and micstr):

1. Move all folders from your old R version to new R version.

/Library/Frameworks/R.framework/Versions/x.xx/Resources/library

Replace x.xx with the old and new R version at a time.

Note that you have to move only the packages that are not currently in the destination folder (because those are the base packages, and you don’t want to ruin them). But if you already did replaced everything, the next step will solve this for you.

If you cannot find the proper path, you can run this command to check: installed.packages()

2. Update the moved packages

Run the following command in R. Type ‘y’ for every question that popped up.

update.packages(checkBuilt=TRUE)

3. Type the following command in R to check if everything went well

version

packageStatus()

That’s it! Hope you guys success in updating R. If not, please check in the reference link below.
