robustmax: Robust maxima

In sjpierce/SSACHR: Serial Sexual Assault Study Criminal History Records Paper Research Compendium

Description

Returns the regular maxima of the input values x using max(x) except it just returns NA when x is an empty vector.

Usage

robustmax(x, na.rm = FALSE)

Arguments

x	Numeric or character arguments.
na.rm	A logical indicating whether missing values should be removed.

Details

=============================================================================

This function solves warnings issued by max() when it is used on an empty vector. Using max(numeric(0)) yields a warning "no non-missing arguments to max; returning -Inf" and is very slow about doing that. So, robustmax() is a replacement function that just returns NA when the vector is empty. That speeds things up dramatically.

Value

A length one vector. The type of the result will be that of the highest of the inputs in the hierarchy integer < double < character.
