randomSubset

Description

Calculates a random subset of the data based on repeated values from a specified column.

Usage

randomSubset(df, colName, seed = NA)

Arguments

df	data frame. Must include a column named by the argument colName.
colName	column name to check for duplicates
seed	integer value. Defaults to NA, which will not change the current seed. Setting the seed to any given value can be used to create repeatable output.
