Thank you but I think not what I would like to get as an answer is the list ("x","v","n","m") + what you gave me could work for 2 fields but if I have 200...

What I want is a vectorize way to do 
bindlists <- function(x){
	output = c();
	for (i in 1:length(x))
		output = c(output,x[[i]])

is this what you're looking for?

test <- data.frame(a=c("x","v"),b=c("n","m"))
