Re: [R] Creating table from data frame

Try this: d <- data.frame(A = letters[1:10], B = sample(letters[11:20]), C = sample(10)) xtabs(C ~ A + B, d) On Tue, Sep 21, 2010 at 8:39 AM, ZeMajik wrote: > Hey, > > I have a dataset where two columns are factors and another column consists > of values. Each combination of factors can only ha

[R] Creating table from data frame
