getMax: Maximum

Description Usage Arguments Details Value Dependencies Author(s)

Description

Computes the maximum value in the sample according to a study variable.

Usage

1
getMax(x)

Arguments

x

is a study variable.

Details

Return the maximum of all the values present in their arguments, as integer if all are logical or integer, as double if all are numeric, and character otherwise.

The maximum of a numeric empty set is +Inf which ensures transitivity. For numeric x ds.max(x) == -Inf whenever ds.length(x) == 0 (after removing missing values if requested).

By definition the max of a numeric vector containing an NaN is NaN, except that the max of any vector containing an NA is NA even if it also contains an NaN. Note that ds.max(NA, Inf) == NA even though the maximum would be Inf whatever the missing value actually is.

Character versions are sorted lexicographically. The max of an empty character vector is defined to be character NA.

Value

The maximum numeric value inside the vector.
