Hi, I cannot any longer load a dataset fom the package nlme. When I try to load the dataset RatPubWeight with the data() command, I get a warning (Warnmeldung: In data(RatPubWeight) : Datensatz 'RatPubWeight' nicht gefunden). With data(package = "nlme") I can see that the dataset RatPubWeight is available in the package. I'm using R version 4.4.2 and the package version nlme_3.1-166. I spent quite an amount of time to overcome this problem but was not successful. Thank you for your help, Stephan Weinbruch [[alternative HTML version deleted]]
