Hi,
I have discovered that sample() fails with an uninformative error
message when the x argument is a single NA of type double or integer.
I can reproduce the problem with the following code:
base::sample(NA)
# NA is of logical type above
base::sample(NA_character_)
base::sample(NA_complex_)
base::sample(NA_real_)
base::sample(NA_integer_)
The last two lines throw the following error:
Error in if (length(x) == 1L && is.numeric(x) && x >= 1) { :
missing value where TRUE/FALSE needed
