hi,
can anyone tell me how to merge a vector and a matrix?
> v=c(1,4,2)
> names(v)=c("e","r","t")
> m=matrix(c("r","t","r","s","e",5,6,7,8,9),nr=5)
> colnames(m)=c("c1","c2")
I want to do like
merge(v, m, by.x="names",by.y="c1")
I got error
Error in fix.by(by.x, x) : 'by' must specify valid column(s)
thanks
jian
