Hi Ken, Without seeing your .csv file or how you are trying to read it, it's tough to diagnose the trouble. I inserted commas between the columns in your data snippet, pasted into Excel, saved as .csv file called "datesfile.csv" in the R working directory. Then, the following worked fine for me: j

Actually, the issue is that the left hand side of the model formula should be the name of the variable under consideration. If you write y ~ 1 there had better be a "y", but without the renaming you could also have used H_to_fit.Height ~ 1. -pd > On 10 Mar 2016, at 19:03 , John Hillier wrote
