Error in aggregate.data.frame(fileIN[, 3], list(fileIN[, 1..: FUN did not
always return a scalar
Dumped
Here is the command that generates the error...
pepar <- aggregate.data.frame(fileIN[,3],list(fileIN[,1],fileIN[,2]),
function(pei) {
#manual trim of 1st and last value
spei <- sort(pei) ; spei[1] <- NA ; spei[length(spei)] <- NA ; spei <-
na.omit(spei)
me <- mean(spei,na.rm=T)
se <- sqrt(var(spei))/sqrt(length(spei)-1)
test <- cbind(me,se)
print(test)
}
)
Any help appreciated
Cheers -Jon
