Hello, I'm trying to use the groupedData function and R is giving me the message: Error: can not find function "groupedData" The code is coming from a textbook so I think it should be correct: pigs<-data.frame(cbind(pig.time,pig.id,pig.wt)) pig.growth<-groupedData(pig.wt~pig.time|pig.id,data=pigs) I have added the package "nlme" and to confirm that it was installed correctly I requested the list of functions included in the package (library(help=nlme)) and I do see groupData in the list. I am using R 2.6.1 in Windows XP. I'll appreciate your help. Thanks, Andrea Previtali Post-doc fellow Dept. of Biology, Univ. of Utah, SLC, UT.
groupedData function not found

Hi Andrea, did you try require(nlme) ? Adding a package is not necessarily the same as loading it. Cheers Andrew
