[R] nominal data

[Bianca]

Hi,

I am a new user of R. I have 2 series of nominal data (2 series of answers
for the same question) and I want to calculate the correlation between these
2 series. I've tried to use the correlation function (corr, ...) but all are
for numeric data... Does anyone know what function should I use for the
nominal data?

Thanks a lot,
Bianca
