you have to use a factor, e.g.,
x <- sample((1:14)[-13], 100, TRUE)
f <- factor(x, levels = 1:14)
table(f)
I hope it helps.

Dear List,
my problem should be easy to fix, but I couldn't find a solution by
myself...
In my survey, there is a question with 14 possible answers. None of the
respondents choose the 13th answer, so when I table() the results, R says:
1 2 3 4 5 6 7 8 9 10 11 12 14
31 52 7 21 40 7 8 2 28 2 2 1 17
13 is missing... anyone knows how to tell table() that there are 14
modalities in the answers? I tried with
responseName=c("1","2","3","4","5","6","7","8","9","10","11","12","13","14")
but all I have is:
error in table....
all the arguments must have the same length
thank you,
Simone
