In mllg/backports: Reimplementations of Functions Introduced Since R-3.0.0
isTRUE R Documentation
Backport of isTRUE for R < 3.5.0
Description
The implementation of 'isTRUE' has been changed in R-3.5.0 from
identical(x, TRUE) to is.logical(x) && length(x) == 1L && !is.na(x) && x.
This backport overloads the old implementation for R versions prior to 3.5.0.
Usage
isTRUE(x)
Examples
# get function from namespace instead of possibly getting
# implementation shipped with recent R versions:
bp_isTRUE = getFromNamespace("isTRUE", "backports")
bp_isTRUE(FALSE)
bp_isTRUE(iris)
