R: Convert Positions in the Search Path to Environments

pos.to.env {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. It is primitive.

Examples

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