I wonder if anyone could help me find an expression for skipping the last
missing values in a vector? The kind of material I have is something like
x-c(23,12,NA,23,24,21,NA,NA,NA)
I would like to skip the last NA's, but not the ones in between other
vallues. Any hints? (Why not do this by simply
A fairly standard trick for such situations is to use
rle(is.na(x))
In your case you want to see if the last value is TRUE.

Do you mean you wish to create a vector without the trailing NAs
but with the others? If so, try:
library(zoo)
head(x, length(na.locf(x, rev = TRUE)))
or
library(zoo)
head(x, length(na.locf(rev(x
