Hi All,
I had 12766 elements in a column, 12566 are values and 200 are "NA"s.
I used the following line to get the ranks:
total_list$MB.rank <-
rank(-total_list$MB,ties.method="min",na.last=NA)
but I got an error message:
Error in `$<-.data.frame`(`*tmp*`, "BCRP_PW_F.rank", value =
c(3949, 6182, :
replacement has 12199 rows, data has 12766
What shall I do to keep the "NA"s as "NA"s? thanks a lot.

Hi, try this: total_list$MB.rank[!is.na(toal_list$MB)] <- rank(-total_list$MB,ties.method"min",na.last=NA) -- Henrique Dallazuanna Curitiba-Paraná-Brasil 25° 25' 40" S 49° 16' 22" O On 17/08/07, Jiong Zhang, PhD <jizhang@chori.org> wrote:> > Hi All, > > I had 12766 elements in a column, 12566 are values and 200 are "NA"s.

You have to select the right option for na.last, and yours is not it. I suspect you want na.last="keep", but only you know what you mean. -- Brian D.
