I am trying to a simple mean imputation using the following command
(yes, I know it is not an ideal way to impute missing data)
asd[is.na(asd)] <- mean(asd,na.rm=TRUE)
This has worked quite well in the past. Now, however, I am getting the
following error messsage.
Error in `[<-.data.frame`(`*tmp*`, is.na(asd), value =
rhs is the wrong length for indexing by a logical matrix
An inspection of the data set reveals no value of the sort give above.
Thanks in advance,
