Well, what's Ret_1 ? It's hard to answer your question without that crucial bit of information.
Try str(Ret_1) and let us know what it says. My first guess is that Ret_1 is a list, e.g.: > testdata <- list(f1=c(1,2,3,4)) > length(testdata) [1] 1 > length(testdata[[1]]) [1] 4 > str(testdata) List of 1 $ f1: num [1:4] 1 2 3 4 But we need more information to actually be able to help you.
