Re: [R] table with 3 variables
Maybe reshape will help you, but I'm in doubt that your posted desired result fits your given data - e.g shouldn't subject 101 Q3 give Y? xx-data.frame(Subject=rep(100:101, each=4), Quarter=rep(paste(Q,1:4,sep=),2), Boolean = rep(c(Y,N),4)) reshape(xx,timevar=Quarter,idvar=Subject,direction=wide,v.names=Boolean) hth.
