I have a dataset that is based on crop output for a single crop *sugarcane*...but each observation is further subdivided into 3 kinds of sugarcane i have read the file and have also used melt it to sort it on the basis of *crop group* using
melt(sugarcane, m=c("Crop_group")) -> canefile this is how it has cast the data variable value 1 Crop_group Sugarcane (first ratoon) 2 Crop_group Sugarcane (planted crop) 3 Crop_group Sugarcane (planted crop) 4 Crop_group Sugarcane (second ratoon) 5 Crop_group Sugarcane (first ratoon) 6 Crop_group Sugarcane (planted crop) now i need to *cast *the data so that i can have each of the 20 odd variables sorted according to the 3 subdivisions under *Crop_group *ie first ratoon), second ratoon etc etc.. i tried using cast (canefile, ~value) -> canefile but it said "Aggregation requires fun.aggregate: length used as default" i want to cast it on all the 20 variables and sort it on the basis of first ratoon, second ratoon and planted crop How i do my CAST command? I hope my question is clear...thanks in advance * * * * -- -- [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
