Dear ASREML users, datafile ! filter 1 ! select 5 will allow me to restrict the data set for only level 5 of the factor in column 1 of datafile; but how can I select levels 1 to 5 inclusive? I can't find the answer in the manual and I've tried a few guesses with no success. Thanks Leigh -- Asreml mailinglist archive: http://www.chiswick.anprod.csiro.au/lists/asreml
