is_empty: Test if vector elements are empty

In jmw86069/genejam: Gene Jam

Test if vector elements are empty

Description

Test if vector elements are empty

Usage

is_empty(x, ...)

Arguments

x	vector that may contain NA values.
...	additional arguments are ignored.

Details

This function simply checks if values in a vector are NA or "" with nchar(x) == 0.

For factor input, the values are coerced with as.character(). It might be slightly faster to test factor levels then to apply to the full vector.

Todo: Make this function work with list input, so it requires all elements to be is_empty().
