Hi all. I have what I'm guessing is a fairly easy question. I want to plot groupedData objects, but there are a large number of subjects in my data. When I use the simple command plot(MyData) where MyData is a groupedData object, there are simply too many individual plots to see anything. I would like, say, 15 per page and for the plots to cover multiple pages. All of the individuals have a different number of time points (this is in a longitudinal context). I wasn't able to find a straightforward solution. On an unrelated note, why does nlsList, for example, return the matrix of coefficients in a different order than the original data set (i.e., the row numbers are all mixed up)? I find it hard to convert this back to the way in which the data were input. I'm guessing there is a good reason, so I'm interested in hearing it.
