[R] combination of different vector values

Thanks in advance for the help.

I have a few vectors and I need to get all the combinations of the vector
Normally I would use a few for-loops to do that.
e.g  x1_c(1,3,5)
     for (i in x1) {
       for (j in x2) {

My problem is that I don't know how many vectors there are ahead of time,
I don't know how many for-loops I need. Any ideas how to implement this?
