Hi, Can anyone recommend one or more good sample datasets for multivariate longitudinal data? (eg. a dataset containing a mixture of continuous, categorical and date/time variables) I'm looking for something which I can use for testing and examples for my ggplot graphics package. A selection of datasets which use different date time classes would also be useful, although I could probably create them myself. I've looked for sample data in chron, its and zoo, but none of them include sample data. Although I haven't looked at the sample data in stats exhaustively, I am looking for something richer and with more observations, than the data typically found there. Thanks, Hadley
