Functions often get passed variables from within dataframes or other lists. However, printing these names with all their dollar signs isn't very userfriendly. This function simply uses a regular expression to extract the actual name.

extractVarName(x)

Arguments

x

A character vector of one or more variable names.

Value

The actual variables name, with all containing objectes stripped off.
