Weighted sampling

Stratified sampling provides rules about the probability of picking rows from your dataset at the subgroup level. A generalization of this is weighted sampling, which lets you specify rules about the probability of picking rows at the row level. The probability of picking any given row is proportional to the weight value for that row.

attrition_pop is available; dplyr and ggplot2 are loaded.
