R help - Jan 2007 - rbind-ing list

hi, 

i have a list of data.frame that has same structure. i would like to know a
efficient way of rbind-ing it. 
right now, i write:


n = length(temp)     # 'temp' is a list of data.frames
temp2 = data.frame()
for (i in 1:n) temp2 = rbind( temp2, temp[[i]])
return(temp2)


but this is not an efficient way since we keeping overwriting temp2. i
wonder if there's faster way. 

thanks
