Hi I have just upgraded from R2.6.0 to R2.7.1 (running on Windows) and a part of my code that previously ran ok now gives an error. The following is a simple example to demonstrate my problem.
> a <- array(c(1,2,3,4,5,6,rep(NA,6)),dim=c(6,2)) > apply(a,2,sd,na.rm=T) In R2.6.0 this gives (which is what I would like) [1] 1.870829 NA In R2.7.1 it gives the following error "Error in var(x, na.rm = na.rm) : no complete element pairs" As my columns are always either all NA or all numbers, I could get around it by replacing the NA's with 0's but if someone could shed some light on why the behaviour has changed in the new version or a better work around it would be much appreciated. I want to keep the columns of NA's because ultimately I am plotting the results with contour and the NA's refer to grid cells not on land where I don't want to have contours.
