Just a handful of functions that are useful to me! Chances are I won't be removing any of them from here but this isn't a "stable" R package by any means...

Index of functions

Plotting helpers

• ggplot_colors() displays the hex codes and physical appearance of the standard ggplot2 color scheme for n groups.

Weighted survey code

• weighted_tabyl() is a weighted data version of janitor::tabyl().

• weighted_crosstab() is a one-liner for some common crosstab machinations done using janitor.

File writers

• writer() writes lines to an output text file.

• chunk_wrapper() wraps writer() to include the standard R chunk notation and options.

secret_chunk_wrapper() is a version of chunk_wrapper() with the defaults to fully hide a chunk (warning, message, include, error, echo are all FALSE).

Negations

• not.null() negates is.null().

• not.na() negates is.na().

• The infix %notin% negates %in%.

Miscellaneous

• read_batch() uses data.table::fread() to read multiple files in the same folder (or zip archive) in one step.
