Hi Dom,
This is because "3" is recycled. It is necessary because the number of
columns have to be the same for every row.
Try this instead:
c(test$a, 2) ## you wrote "3" but meant "2" I guess
HTH,

Dear R-community,
When doing this:
test<-data.frame(a=c(1,2,3))
rbind(test$a, 3)
I expect something like:
1
2
3
2
but get:
[,1] [,2] [,3]
[1,] 1 2 3
[2,] 2 2 2
the same for:
rbind(test[["a"]], 2)
or
rbind(as.vector(test[["a"]]), 2)
or
rbind(t(as.vector(test[["a"]])), 2)
Why is that and how do I extract the "values" from a dataframe to get the
desired result?
Thank you
Dom
