R help - Oct 2007 - replacing NA's with various numbers

Hi 
I have two vectors in the same style as
x<-c(NA,NA,1,3,4,NA,1)
y<-c(0,0,NA,NA,NA,0,NA)

that is when x[ i ] = NA,  y[ i ]=numeric. I wish to replace the NA's in x
by the corresponding y value. Any help would be much appreciated.
Nigel

x[is.na(x)]<- y[is.na(x)] but this will only work correctly if x and y
are the same length so I hope that is
what you mean by the same style.
