In fastplyr: Fast Alternatives to 'tidyverse' Functions

Fast versions of tidyr::expand() and tidyr::complete().

Description

Fast versions of tidyr::expand() and tidyr::complete().

Usage

f_expand(.data, ..., .sort = FALSE, .by = NULL, .cols = NULL)

f_complete(.data, ..., .sort = FALSE, .by = NULL, .cols = NULL, fill = NA)

crossing(..., .sort = FALSE)

nesting(..., .sort = FALSE)

Arguments

.data	A data frame
...	Variables to expand.
.sort	Logical. If TRUE expanded/completed variables are sorted. The default is FALSE.
.by	(Optional). A selection of columns to group by for this operation. Columns are specified using tidy-select.
.cols	(Optional) alternative to ... that accepts a named character vector or numeric vector. If speed is an expensive resource, it is recommended to use this.
fill	A named list containing value-name pairs to fill the named implicit missing values.

Details

crossing and nesting are helpers that are basically identical to tidyr's crossing and nesting.

Value

A data.frame of expanded groups.
