when all I have is a contingency table....
See Teds answer for histogram (I'd go with barplot). For most statistical procedures there is a weighted version (e.g. weighted.mean() for the mean). Your counts are valid weights for most procedures. Cheers Joris

Hello, I just need a hint here: Suppose I have no raw data, but only a frequency table I have, and I want to run basic statistical procedures with it, like histogram, descriptive statistics, etc. How do I do this with R? For example, how do I plot a histogram for this table for a sample of size 60? Value ? Count 1 ? ? ? 10 2 ? ? ? 8 3 ? ? ? 12 4 ? ? ? 9 5 ? ? ? 14 6 ? ? ? 7 Thanks, A.Z.
