extraction from a list of vectors

Hi , 
I know this should be easy, but I haven't figured out a fast way to
do it. 
I have a list of vectors: mylist <- list(vector1, vector2, ...,
vectorN). 
(The vectors are made of integers. They vary in length from about 1
to 10). 
I also have a vector of indices: myidx <- c( i1, i2, ..., iN). 
From these I'd like to make this: newvector <- c(vector1[i1],
vector2[i2], ..., vectorN[iN]). 

I don't know if this is fast or not, but I think it gives the result
you want:

unlist(sapply(myidx,function(x) mylist[[x]]))
