replaceMissingWithTRUE: Replace missing elements with TRUE
Description
When subsetting, missingness stands in for selecting all of the elements of that
dimension. This gets tricky when you are selecting n dimensions and so need to
capture the dimensions with ...
. This function checks if an element of a list
is missing and replaces that element with TRUE
in order to handle this case.
Usage
replaceMissingWithTRUE(l)
