Hi guys,
I hope you can help me with this.
Here is the problem:
I have some data (myData) that looks similar to this:
[,1] [,2] [,3] [,4]
[1,] "A" "A" "B" "B"
[2,] "B" "B" "B" "B"
[3,] "C" "C" "C" "C"
When I build a contingency table for the first and second row using:
tb <- table(myData[1, ], myData[2, ], useNA="ifany")
I get:
B
A 2
B 2
But - I would like to also see "C" there (with a zero).
Actually, I would like to give a list of n characters that would be used to
build an n*n table and the data for this table should then come from myData
(and if there are characters in my list that do not appear in the data at
all I would like to see a zero row or a zero column).
Is that possible to do?
What would be the simplest way?
Many many thanks!!!
Liat.
