[R] Making Sure your matrices are even

[David Carlson]

Try this

S2 <- data.frame(Group=rep("S", length(S)), Cat=factor(S))
B2 <- data.frame(Group=rep("B", length(B)), Cat=factor(B))
V2 <- data.frame(Group=rep("V", length(V)), Cat=factor(V))
table(rbind(S2, B2, V2))

Subject: [R] Making Sure your matrices are even

Hi,

I am trying to do a chi sqaure on a set of values, and my
different groups
are not even. Is there away to add arbetrary symbols or #s to
make the
matrices even? Or do I need to do a different type of pvalue
analysis?

> S<-1:86
> B<-1:15
> V<-1:45
> table(S)
