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 -- View this message in context: http://www.nabble.com/rbind-ing-list-tf3140137.html#a8703373 Sent from the R help mailing list archive at Nabble.com.
