That depends on _how_ you want the (pseudo-)random numbers to be distributed
within the range.  If you want uniform (i.e., all numbers within the range
equally likely to be sampled), use something like runif(1000, 1, 41).  If
you want the discrete (i.e., only integers) version, use sample(1:41, 1000,
replace=T).
