[R] Append data to vector form a column of a dataframe

[behave]

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
