is an internal RLink variable that stores a value of the search path (a list of directory names) where RLink will look for definitions of user-defined data types.


  • By default, the value of is a list of a single directory, pointing at the "/Kernel/DataTypes" subdirectory within the RLink distribution.
  • While this variable can be manipulated directly, it is not recommended. A preferred way to add more locations to the RLink data type search path is to do so via the "AddToRDataTypePath" option of InstallR function, when installing RLink.
