getstack {cgwtools}

Returns the current directory stack that pushd and popd manipulate

Description

getstack goes into the separate environment where pushd and popd operate and returns the current stack of directories.

Usage

getstack()

Arguments

none

Details

Allowing a function to modify an object in the GlobalEnvironment is frowned upon by CRAN (and most programmers), so to maintain a directory stack a separate environment is established by pushd. Since this environment is not visible at the console level, getstack allows the user to check on the current status of the stack.

Value

The current directory stack is returned as a vector of strings.
