Usage

swap_by_ids(swap_list, variable, data = get_data())

Arguments

swap_list	list. A list mapping ids to the value that id should have e.g., list(1 = 'cat', 2 = 'dog', 3 = 'dog')
variable	character. The name of the variable where the replacement occurs.
data.	The data to be transformed. This is assumed to be a three column melted dataframe, using reshape2 <http://cran.r-project.org/web/packages/reshape2/index.html>.
