Subject: Force "square" crosstabulation
Hello list members,
I'm looking for a way to force the results of a crosstabulation to be
square - that is, to include 0 values.
For example:
table(letters[1:4],letters[c(1:3,3)])
yields:
a b c
a 1 0 0
b 0 1 0
c 0 0 1
d 0 0 1
I would like to return:
a b c d
a 1 0 0 0
b 0 1 0 0
c 0 0 1 0
d 0 0 1 0
Any suggestions?
Thanks!
