InstallR

InstallR[opts]

starts up the R runtime and connects to it.

Details and Options

  • InstallR must be called before any work can be done with the RLink.
  • The following options can be given:
  • "JRELocation"Automaticpath to a custom Java Runtime Environment (JRE)
    "RCommandLine"Automaticlist of strings starting with "--" and representing command-line arguments for R
    "RHomeLocation"Automaticlocation of the root of an external R distribution (currently Windows only)
    "AddToRDataTypePath"Nonelist of directories with external data type definitions
    "ConfigureAutomatically"Trueenables automatic configuration of the R distribution upon the first use
    "RVersion"Automaticversion of the R system to connect to; must be a string
    "JRINativeLibraryLocation"Automaticpath to the folder containing the native JRI library compatible with the given external R distribution
  • If the "RHomeLocation" option is not set, InstallR will ignore possible settings of options "JRINativeLibraryLocation" and "RVersion" and attempt to use the last R distribution to which it has successfully connected. If either no such connection took place or the current connection attempt fails, it will search for all available R distributions and try connecting to each of them in turn until a successful connection is established. If InstallR fails to connect to any of the found R distributions or if none were found, it returns $Failed, with an appropriate error message.
  • If "RHomeLocation" is set to a specific location, this enables RLink to use an external R distribution, where the specified location should correspond to the setting of the R_HOME variable (which points at the root of the R distribution).
  • If the R runtime has already been installed, InstallR does nothing when called with the same value of the "RHomeLocation" option and issues a warning message if that value points to a different R distribution than the one currently in use. In either case, it keeps running the current active R session.
  • RLink searches in directories specified with "AddToRDataTypePath" for external data type definitions, which are user-defined data types extending core RLink type system. When found, such definitions are loaded by InstallR and registered with RLink.
