R help - Apr 2024 - Problem with base::order

Hi,

when I execute

order(letters, LETTERS, 1:26)

then everything is fine. But if I execute

order(letters, LETTERS, 1:26, na.last=c(T,T,T), decreasing=c(F,F,F))

I get the error message

Error in method != "radix" && !is.na(na.last) :
'length = 3' in constraint to 'logical(1)'

Shouldn't both give the same result?

This is only documented to work with method = 'radix':

I think this is supposed to be a scalar, no matter the sort method. At
the very least, I don't see it documented to accept a logical vector,
and the C code in both src/main/sort.c and src/main/radixsort.c treats
the argument as a scalar (using asLogical(...), not LOGICAL(...) on the
R value).
