Description Usage Arguments Examples

Sometimes you want a small sample of a data frame — as with head() — but you want as many different levels of the variables as possible to be included. This function takes a sample from a dataframe, arranging things so that as many distinct levels as possible of each value for each variable are kept. The incoming random seed will be restored when the function exits.
