R is a computer language. It’s a tool for doing the computation and number-crunching that set the stage for statistical analysis and decision-making. RStudio is an open source integrated development environment (IDE) for creating and running R code. It’s available in versions for Windows, Mac, and Linux. Although you don’t need an IDE in order to work with R, RStudio makes life a lot easier.

Welcome to r/mac, the place for all things Mac, iMac, and MacBook. Feel free to ask questions, share your problems, or discuss Apple's computers. Please do not self promote or post ads. You should not be gaining off a post unless you are trouble shooting. Windows and Mac users most likely want to download the precompiled binaries listed in the upper box, not the source code. The sources have to be compiled before you can use them. If you do not know what this means, you probably do not want to do it! The latest release (2018-07-02, Feather Spray) R-3. Load more results.

This is the piece of software that I used to fix this problem on a customers machine.Go here; and download the free version.now use the Rebuild function to fix the problem. /iphoto-90-dmg.html.

Download R from the Comprehensive R Archive Network (CRAN). In your browser, type this address if you work in Windows:

cran.r-project.org/bin/windows/base/

Type this one if you work on the Mac:

cran.r-project.org/bin/macosx/

Click the link to download R. This puts the win.exe file in your Windows computer, or the .pkg file in your Mac. In either case, follow the usual installation procedures. When installation is complete, Windows users see an R icon on their desktop, Mac users see it in their Application folder.

Both URLs provides helpful links to FAQs. The Windows-related URL also links to “Installation and other instructions.”

Now for RStudio.

Click the link for the installer for your computer, and again follow the usual installation procedures.

After the RStudio installation is finished, click the RStudio icon to open the window shown.

If you already have an older version of RStudio and you go through this installation procedure, the install updates to the latest version (and you don’t have to uninstall the older version).

The large Console pane on the left runs R code. One way to run R code is to type it directly into the Console pane.

The other two panes provide helpful information as you work with R. The Environment and History pane is in the upper right. The Environment tab keeps track of the things you create (which R calls objects) as you work with R. The History tab tracks R code that you enter.

Get used to the word object. Everything in R is an object.

The Files, Plots, Packages, and Help tabs are in the pane in the lower right. The Files tab shows files you create. The Plots tab holds graphs you create from your data. The Packages tab shows add-ons (called packages) you downloaded as part of the R installation. Bear in mind that “downloaded” doesn’t mean “ready to use.” To use a package’s capabilities, one more step is necessary, and you’ll want to use packages.

This figure shows the Packages tab. The packages are in either the user library (which you can see in the figure) or the system library (which you have to scroll down to).

The Help tab, shown here, provides links to a wealth of information about R and RStudio.

To tap into the full power of RStudio as an IDE, click the larger of the two icons in the upper right corner of the Console pane. That changes the appearance of RStudio so that it looks like this:

The top of the Console pane relocates to the lower left. The new pane in the upper left is the Scripts pane. You type and edit code in the Scripts pane and press Ctrl+R (Command+Enter on the Mac), and then the code executes in the Console pane.

Ctrl+Enter works just like Ctrl+R. You can also select Code → Run Selected Line(s).

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:

• 'Convert archives' command:
  • improved performance when processing a lot of small archives in Windows 10;
  • fixed memory leaks which could lead to excessive memory use when converting to ZIP format.
• Corrupt ZIP archive processing:
  • 'Repair' command replaces packed and unpacked file sizes stored in local file header with sizes from central directory if local header sizes look invalid;
  • file extraction is stopped at unpacked size stored in ZIP headers even if available packed data allows further extraction. It is done to prevent unexpected hard drive space usage.
• Ctrl+C allows to abort RAR 'l' command quickly. In previous versions it could take several seconds until list command stopped.

Bugs fixed:

• WinRAR could crash when attempting to display some types of archive comments in GUI shell, resulting in a denial of service;
• if 'Save archive name' and 'Add to context menu' options were set in compression profile parameters and profile was invoked from Explorer context menu, WinRAR proposed an automatically generated archive name instead of name saved in profile.
• WinRAR displayed an unneeded pair of round brackets in 'Archive' column of 'Diagnostic messages' window for system error messages;
• 'Extract to folder' Windows Explorer context menu command could fail to unpack ZIP archives if their names included a numeric part followed by .zip extension, arbitrary data was present before the first file record and 'Remove redundant folders from extraction path' WinRAR option was switched on;
• in 'RAR x -xarcname' command, parent folders of files matching the specified mask also were excluded from extracting;
• 'Find' command returned the current folder own name additionally to its contents for 'Current folder' search area if folder name matched 'File names to find' mask;
• if 'Find in files' and 'Find in archives' are both enabled, 'Find' command did not match an archive name itself against 'File names to find' mask after searching inside of archive. So it did not display archive names for masks like *.rar and applied this mask only to files inside of archives;
• when running an executable directly from archive, WinRAR 5.70 did not set a temporary folder with unpacked files as current. So executables attempting to access other archived files in current folder could fail to work;
• WinRAR could be inaccessible for few seconds after closing an archived file opened in internal viewer in Windows 10;
• dragging a file to subfolder of ZIP archive with 'Store full paths' option enabled produced invalid pathnames consisting of repeated subfolder name. Same invalid pathnames were produced if adding files to ZIP archive with -ap -ep2 switches.
