...to work together with me on an English version in the future. It is work in progress, so please excuse typos and mistakes (some PDF errors are already known). On the other hand, I would be very glad about remarks and constructive criticism. The tutorial can be found on http://www.tu-dresden.de/fghhihb/petzoldt/zeugs.html together with an absolutely preliminary version of an accompanying library (the name simecol may be changed soon). Thank you for your feedback! Many thanks to all the people who are making the R-project possible! Thomas -- Thomas Petzoldt Tel. +49-351-4...

Hi Does anybody know of any R packages under Windows to produce video files from a sequence of R graphs -- e.g. in .wmv or avi format? Thanks David

Hi, Does any one knows how to include greek letters in plot labels and plot titles ? Thanks a lot paul --- [[alternative HTML version deleted]]

Hi, I am almost new to R. Would any one show me (please include an example) how to clip a contour or image figure so that I only see the image or lines inside a selected area?

Hi all, I think this question could be quite trivial, but I can?t find out the solution... How can you compute the statistic "mode" of a sample, in case it exists (as mode() returns the mode of an object)? I tried help.search("mode") but I couldn't find a clue... Any help would be much appreciated. Regards, Aurora

hi all i have another probably simple question. I have three variables say x, y and z. x and y are quite large and z is relative small. how can one plot the three variables on the same graph with two separate axis? (one for x and y and the other for z) e.g. x<-c(101,110,150,167,120) y<-c(120,135,175,95,200) z<-c(0.001, 0.15, 0.6, 0.8, 1) regards Allan

Hi - I am getting different results when I run the numerical integrator function lsoda (odesolve package) on a Mac and a PC. I am trying to simulating a system of 10 ODE's with two exogenous pulsed inputs to the system, and have had reasonably good success with many model parameter sets. Under some parameter sets, however, the simulations fail on the Mac (see error message below). The
