You need to include how many random numbers you want to create; you
are asking for only 1, that is why they are are the same. You
probably want something like:
,sample(1:4, nrow(a), TRUE)
,sample(5:9, nrow(a), TRUE)
,sample(10:12, nrow(a), TRUE)
, -42 # you had a character which would have converted
everything to character
