Hi,
I am trying to get a summary of the counts of different variables for each
sample in a matrix of the form "m" below to generate an output as shown.
(Ultimately I want to generate a stacked barchart for each sample). I am only
able to get the "table" function to work on one sample (column) at a time. Any
help appreciated.
Thank you
Sarah
a<-c("A", "A", "B", "B", "C", "A", "C", "D", "A", "D", "C", "A", "D", "C", "A",
"C")
m<-matrix(a, nrow=4)
m
[,1] [,2] [,3] [,4]
[1,] "A" "C" "A" "D"
[2,] "A" "A" "D" "C"
[3,] "B" "C" "C" "A"
[4,] "B" "D" "A" "C"
output needed (so that I can use the "barplot(t(output))" function):
A B C D
[,1] 2 2 0 0
[,2] 1 0 2 1
[,3] 2 0 1 1
[,4] 1 0 2 1
