Dear Celine If you are considering using support vector machines in R, you might find it worthwhile to read the paper:

Dear All, Apologies for sending this email to both list, but at this point I'm not sure which one could help me the most. I have 4 sets of data, 1 test and 3 different sets of controls. The measurements are binary, with a matrix of 0 and 1 I'm measuring across time (rows, ~815) the behaviour of organelles in the cell by microscopy in response to different stimuli (several measurements for each set, 57 columns in total) Set 1: parasite test Set 2: no stimulus Set 3: inert stimulus (beads) Set 4: different pathogen Across time, a "zero" means nothing happens around my parasite introduced in the cell, a "1" means some cytoskeleton dynamics occurring around my parasite I want to give some statistical value to my observations in saying that the cytoskeleton dynamics are specific to my parasite at that frequency across time. I thought of comparing profiles, like a smooth profile to summarise all that is happening in each set and test for distances between 2 smoothed sets. But the timig when something is happening varies a lot, sometimes it's few seconds, sometimes minutes, sometimes only once per measurements, sometimes more for the same parasite.. I'm not sure how to proceed. I have been looking into e1071 package in R for support vector machine, but I'm not sure this will give me the right model. I am very grateful for any help / advice anyone can think of Thank you very much Celine
