Hi. Here are some examples that could be useful here: set.seed(1) x <- sample(1:2, 100, rep=T) y <- sample(1:3, 100, rep=T) TAB <- table(x,y)
#check the object class class(TAB) apply(TAB, 2, max) apply(TAB[,2:3], 2, max) apply(TAB, 1, max) DF <- as.data.frame.matrix(TAB) class(DF) sapply(DF, max) Look at ?class, ?table, ?"[" , ?apply, ?as.data.frame.matrix and read posting guide.
