R help - Feb 2013 - How to stack row vector on top of each other?

Hi list,
How do you actually stack a vector on top of each other?  Say, I want
everything in a row vector.  Neither rbind(), nor cbind() will do the job.
 It gives me 2 dimension.

Here's my reproducible example:
> a <- rnorm(10)
> b <- rnorm(10)
> c <- cbind(a,b)
> dim(c)
[1] 10  2
> d <- rbind(a,b)
> dim(d)
[1]  2 10

Thanks,
Mike

Hi,

Actually, ?"c"

 > a <- rnorm(10)
 > b <- rnorm(10)
 > d <- c(a,b)
 > length(d)
[1] 20

HTH,
Pascal

I guess I don't know what you mean by "actually stack a vector on top
of each other".  Given the vectors

a <- 1:3
b <- 4:6

What result do you want from "stacking" a and b?
