Set Environment Variables

Description:

     `putenv' sets environment variables (for other processes called
     from within R or future calls to `Sys.getenv' from this R
     process).

Usage:

     Sys.putenv(...)

Arguments:

     ...: arguments in `name=value' form, with `value' coercible to a
          character string.

Details:

     Non-standard R names must be quoted: see the Examples section.

Value:

     A logical vector of the same length as `x', with elements being
     true if setting the corresponding variable succeeded.

Note:

     Not all systems need support `Sys.putenv'.

See Also:

     `Sys.getenv', `setwd' for the working directory.

Examples:

     print(Sys.putenv("R_TEST"="testit", ABC=123))
     Sys.getenv("R_TEST")
