Filter, partition, and sort dataframes in Chez Scheme

This post is the fourth in a series on the dataframe library for Chez Scheme. In this post, I will contrast the dataframe library with functions from the dplyr R package for filtering, partitioning, and sorting dataframes.

Split, bind, and append dataframes in Chez Scheme

This post is the third in a series on the dataframe library for Chez Scheme. In this post, I will contrast the dataframe library with functions from base R and the dplyr package for splitting, binding, and appending dataframes.

Select, drop, and rename dataframe columns in Chez Scheme
