Why don't you ask your "someone at work" to help, as you appear to have local resources handy?

So, a snippet of the data looks like this: TrialNo Drug Sex Rand Adate1 Date1 Dose1 Time1 Adate2 Date2 Dose2 Time2 B1001029 LTG M 15719 30/04/2003 15825 150 106 29/08/2003 15946 200 227 B1117003 LTG M 15734 30/04/2003 15825 200 91 03/09/2003 15951 250 217 B138015 LTG M 14923 06/02/2001 15012 225 89 08/05/2001 15103 300 180 B112003 TPM F 14914 15/01/2001 14990 60 76 05/03/2001 15039 100 125 Of course, not everyone has the same number of follow-up appointments and so there may be some column entries that are NAs. What I'd like to do is a dose profile i.e. a plot of time on the x-axis agaisnt dose on the y-axis for each patient ideally colouring lines according to drug. Does anyone know how I can do this? Someone at work has suggested that I use plot and then loess.smooth but I don't really know what to do. Thank you very much for your help, Laura [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
