Subject: RE: [R] Replace missing value within group with non-missing value
Hi Rui,
I have just pasted this direct and rerun. I still get the same error.
I am running this on the full length dataset.
dim [1] 255030 5
I attach the first few rows of the file.
Error pasted below.
I am using version 2.15.2 on a windows 7 machine.
> sp <- split(dat, list(dat$dn, dat$obs))
> names(sp) <- NULL
> tmp <- lapply(sp, function(x){
+ idx <- which(!is.na(x$mth))[1]
+ if(length(idx) > 0)
+ x$mth <- x$mth[idx]
+ x
+ })
Error in `$<-.data.frame`(`*tmp*`, "mth", value = NA_real_) :
replacement has 1 rows, data has 0
> do.call(rbind,tmp)
Error in do.call(rbind, tmp) : object 'tmp' not found
Any thoughts on what could be causing this anomaly?

Hello,
I've just run my code with your data and found no error. Anyway, try replacing
the lapply instructi
on with this.
tmp <- lapply(sp, function(x){
idx <- which(!is.na(x$mth))[1]
if(length(idx) > 0)
x$mth <- x$mth[idx]
x
})
