Dear R users, I have a dataframe like this:
x1<-c(1,2,3,4,NA ,NA ,NA, 3, 1, 1, 1, 1, 2, 2, 3, 4, 4) x2<-c(2,3,4,3,4,3,4,2,2,3,4,NA,NA,NA,NA,4,3) x3<-c(1,1,1,1,2,2,2,2,3,3,3,3,4,4,4,1,2) m<-data.frame(x1,x2,x3) I would like to create a frequency table like this: x1 x2 x3 NA 1 2 3 4 where the values in each cell would be the count of the value for that variable. How can I do this? Thanks for the help.
