R help - Jan 2005 - Adding values to the end of a vector?

I want to add values onto the end of a vector, for example...

x <- vector

for (i in 1:5){
  add_to_end_of_vector(i,x)
}

I just cant find the answer to this question!


Sorry for such a basic question, I tried...

x <- c()

for (i in 1:5) x[length(x)] <- i

but it didn't work.

Is this what you're looking for?
> x <- numeric(0)
> for (i in 1:5) x <- append(x, i)
> x
[1] 1 2 3 4 5

The following works, but there may be more efficient ways to do this ...
> x=numeric(0)
> for(i in 1:5) { 
+ x[length(x)+1]=i
+ }
> x
[1] 1 2 3 4 5

Best, ingmar
