InstallR[opts]
installs RLink.
Details
must be called before any work can be done with the RLink.- The following options can be given:
-
"JRELocation" Automatic path to a custom Java Runtime Environment (JRE) "TargetPlatform" Automatic name of the platform, if different from $SystemID "RCommandLine" Automatic list of strings starting with "--" and representing command-line arguments for R "RHomeLocation" Automatic location of the root of an external R distribution "AddToRDataTypePath" None list of directories with external data type definitions "EnableResourcesAutoinstall" True enables automatic download and installation of the RLinkRuntime paclet, if the latter has not yet been installed - The "TargetPlatform" option should only be used under rather special circumstances, such as when you would like to use the 32-bit version of R on a 64-bit machine (note that in such a case, you will also need to use the "JRELocation" option, to indicate the path to 32-bit JRE).
- If the R runtime has been already installed,
does nothing. - If "RHomeLocation" is set to a specific location, this enables RLink to use external R distribution, where the specified location should correspond to the setting of the R_HOME variable (point at the root of R distribution).
- RLink searches in directories specified with "AddToRDataTypePath" for external data type definitions, for user-defined data types extending core RLink type system. When found, such definitions are loaded by
and registered with RLink. - If the RLinkRuntime paclet (which contains R distribution bundled with RLink) has not yet been installed on your system, and if the "EnableResourcesAutoinstall" option is set to True, the RLinkResourcesInstall function is automatically called by
. This does not happen, however, if you indicate the location of your own R distribution with the "RHomeLocation" option.
