Did you try it? I said library(zoo) na.locf(P, fromLast=TRUE)
Note the 'fromLast=TRUE'; that tells na.locf() to use the reverse of your vector. What I meant by "You'll have to decide what to do if the last value is NA" is that you'll need to decide what to do if your vector ends with a NA, say: v [1] 1 9 NA 4 5 20 NA 15 8 NA -Peter Ehlers anna wrote:
