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

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,]123 >[2,]222 the same for: rbind(test[["a"]], 2) or rbind(as.vector(test[["a"]]), 2) or rbind(t(as.vector(
