The main R FAQ can be found at. The information here applies only to recent versions of R for Windows. It is biased towards users of bit Windows and since R 4. These are frequently updated builds of development versions of R.
Current binary versions of R are known to run on Windows 7 or later. Windows XP is no longer supported. For UTF-8 to be the native encoding, you need R at least 4. Your file system must allow case-honouring long file names as is likely except perhaps for some network-mounted systems. An installation takes up to MB of disk space. We tried to make R to work with space in file names, but building of some packages from source may not work as this is little tested.
You can check whether the short name is available from R by shortPathName R. If it is not, you may create it using fsutil , e. This may also be needed by some other applications used from R packages. We have come across Windows Server docker container images with short names disabled even on the system drive. Just double-click on the icon and follow the instructions. If you have an account with Administrator privileges you will be able to install R in the Program Files area and to set all the optional registry entries; otherwise you will only be able to install R in your own file area.
Since R 4. Prior to R 4. Once R is installed, one may open the installation directory in explorer using shell. After installation you may choose a working directory for R.
You will have a shortcut to Rgui. Right-click each shortcut, select Properties Also, you need to remove the argument --cd-to-userdocs in the Target field, which implements the default behavior. If your account was not the one used for installation, you may need to copy the shortcut before editing it. On some systems with R prior to 4. You may also want to add command-line arguments at the end of the Target field after any final double quote, and separated by a space , for example --sdi --no-environ.
The normal way to customize the installation is by selecting components from the wizards shown by the installer. However, sysadmins might like to install R from scripts, and the following command-line flags are available for use with the installer.
A successful installation has exit code 0: unsuccessful ones may give 1, 2, 3, 4 or 5. The command line can be anything you would put in the Target field of a shortcut, and the starting directory will be the current working directory of the shell.
People running from a terminal usually prefer to run Rterm. Yes, with care. A basic R installation is relocatable, so you can burn an image of the R installation on your hard disc or install directly onto a removable storage device such as a flash-memory USB drive. Running R does need access to a writable temporary directory and to a home directory, and in the last resort these are taken to be the current directory. This should be no problem on a properly configured version of Windows, but otherwise does mean that it may not be possible to run R without creating a shortcut starting in a writable folder.
If it does not appear there, run unins Uninstalling R only removes files from the initial installation, not for example packages you have installed or updated in your personal library. For most people the best thing to do is to uninstall R see the previous Q , install the new version, and then there are two options what to do with the library. The simpler but more resource intensive one is to install all required packages again with the new version of R and then delete the old library once you no longer need it e.
Sometimes, this is necessary when there is a change in R that makes the installed packages incompatible, such as when upgrading from R 4. Also, installing packages can be very fast when they are distributed in binary form e. A previously recommended option was to copy any installed packages to the library folder in the new installation, run update.
Different versions of R are quite deliberately installed in parallel folders so you can keep old versions around if you wish. This would often work, but not e. Create a separate shortcut for each project: see Q2. Alternatively, start R by double-clicking on a saved. RData file in the directory for the project you want to use, or drag-and-drop a file with extension. RData onto an R shortcut. In either case, the working directory will be set to that containing the file.
You can also set up a batch file using Rterm. A sample batch file might contain as one line. You can find this from R code by the call getwd. Otherwise if environment variable HOME is set, its value is used. After those two user-controllable settings, R tries to find system-defined home directories.
If all of these fail, the current working directory is used. You can find the home directory from R code by Sys. Note that some distributions of Unix utilities for Windows, such as Msys2 and hence Rtools or cygwin set the environment variable HOME to a user directory of their choice. When R is invoked from a shell of such an distribution, the home directory in R would hence typically not be the Windows "personal" directory.
With Rtools40 and Rtools42, it is the user profile e. The R home directory is the directory where R was installed. You can find this from R code by R. Environment variables can be set for Rgui. This is useful for variables which should be set for all users and all usages of this R installation. Their values can be overridden in a. Renviron file or on the command line. Startup for more details of environment files and specifically pay attention to caveats when using backslashes.
The order of precedence for environmental variables is the order in which these options are listed, that is the command line then. Renviron then the inherited environment. How did you specify it? You can make life easier for yourself by using forward slashes as path separators: they do work under Windows.
You should include the file extension e. A simple way to avoid these problems is to use the function file. If you select a file there, the name will be passed to R in the correct format. Another possible source of grief is spaces in folder names.
We have tried to make R work on paths with spaces in, but many people writing packages for Unix do not bother. See also Q2. After installation you can add the Registry entries by running RSetReg. Directly, no. We have had several reports of this, although they do work for us on all of our machines. There are two known possible causes.
This has not been reported for many years, but used to happen regularly. This is a warning which indicates that R has taken action to correct the action of some non-R DLL which has just been loaded and has changed the floating point control word in its initialization code to a setting incompatible with that needed for R.
This is not good practice on the part of the DLL, and often indicates that it needs to be updated. We may be able to remove this handling of the FPU control word in future versions of R. Some users have found that Rgui. This error may also happen in the middle of a session. In some cases where we have tracked this down, it was due to bugs in the video driver on the system in question: it makes changes to the floating point control word which are incompatible with R.
Good practice would restore the control word to the state it was in when the driver code was called, and R tries hard to correct this before running its own code. For example, one user reported that the virtual screen manager JSP2 caused this crash.
These errors are essentially impossible for us to fix or work around beyond the measures already taken. The only solution we know of is for the user to replace the buggy system component that is causing the error. What the task manager shows is not the usage in CPUs but the usage as a percentage of the apparent total number of CPUs. R itself would only use multiple CPUs during parallel installation of packages, which needs to be selected by user.
Some contributed R packages use multiple CPUs or multiple threads. Some performance work-arounds for old Windows systems past their end of support may be removed, such as a custom memory allocator removed in R 4.
R would be installed either by users in their own file space or by an account with administrator privileges into a system area. The Administrator account by default has it turned off. Unlike say Windows XP, such accounts do not run programs with full administrator privileges, and this is where the issues arise. System administrators can disable installing applications from non-trusted sources, in which case you will have to persuade them that R is trustworthy, or digitally sign the R installer yourself, or unless this is also disabled run the installer from a standard account and install into your own file area.
