pos.to.env               package:base               R Documentation

Convert Positions in the Search Path to Environments

Description:

     Returns the environment at a specified position in the search
     path.

Usage:

     pos.to.env(x)

Arguments:

       x: an integer between 1 and 'length(search())', the length of
          the search path.

Details:

     Several R functions for manipulating objects in environments (such
     as 'get' and 'ls') allow specifying environments via corresponding
     positions in the search path.  'pos.to.env' is a convenience
     function for programmers which converts these positions to
     corresponding environments; users will typically have no need for
     it.

Examples:

     pos.to.env(1) # R_GlobalEnv
     # the next returns the base environment
     pos.to.env(length(search()))
