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' (although all known
     current platforms do).

See Also:

     'Sys.getenv', Startup for ways to set environment variables for
     the R session.

     'setwd' for the working directory.

Examples:

     print(Sys.putenv(R_TEST="testit", "A+C"=123))
     Sys.getenv("R_TEST")
