edwards

A package of miscellaneous R functions I wrote for general data science use.

Although most functions work well and are stable, I regard these as still being in development and breaking changes are to be expected. They are intended for interactive use.

• Counting functions. These begin with count_ and count NAs, levels, matches, string patterns, or unique values by column in a data frame. var_summary() performs a number of these counts and puts the results in a table. count_over() gives a shortcut to use dplyr::count() over several variables.
• Utility functions: mode_stat() (statistical mode), factor_to_numeric() (factor conversion), ilogit() (inverse logit function), object_size_all() (summary of memory used by objects), and diff_days() (difference in days between two dates), and min_n()/max_n().
• Data cleaning helpers:na_if_any()/na_if_string() to replace NAs, is_simple_datetime() to simplify datetimes.
• Binning functions. bin_integer() and bin_integer_fct() for converting integer vectors to binned factors with appropriate level names.
• Kable helpers: my_kable(), kbl_ctable(), and split_kable().
• Comparison functions. compare_vars() and compare_vecs() give pairwise similarity and ordering of two variables; find_similar() looks for matched or similar columns within a data frame or across two data frames; compare_sets() counts differences between two sets.
• Directory functions: dir_contents(), dir_size(), and dir_files() give info on the contents of a directory.
• Data relation tools: fd_cols() and is_one2one() to find functional dependencies and one-to-one relationships in a data frame.
• latest_file() gets path of the "most recent" file in a folder based on its name.
• count2() and vcount() adapt dplyr::count() to give more information or to work with atomic vector inputs.
• Some minor helper functions to save a bit of typing: count_n() and prinf().
