Hello R-Users! I need a little help to build up a contingency table out of several variables.
A<-c("F","M","M","F","F","F","F","M","F","M","F","F") B<-c(0,0,0,0,0,0,1,1,1,1,0,1) C<-c(0,1,1,1,1,1,1,1,1,0,0,0) ABC<-as.data.frame(cbind(A,B,C)) ABC A B C 1 F 0 0 2 M 0 1 3 M 0 1 4 F 0 1 5 F 0 1 6 F 0 1 7 F 1 1 8 M 1 1 9 F 1 1 10 M 1 0 11 F 0 0 12 F 1 0 I would like to count in each variable B and C the frequencies for M and F (variable A) and finally get the following table: B C F 3 5 M 2 3 Is there a function that can do that in one step? Tried ?structable, ?ftable, ?xtabs, ?table but could not get what I would like to have. Maybe I did not use the tried functions in the right way. Many thanks in advance for any help.
