Hello I've just realised attachments are not allowed, so the data for the example in my previous message is:
pos.df=read.table("http://www.savefile.com/projects3.php?fid=6240314&pid=847249&key=119090", header=T) neg.df=read.table("http://fs07.savefile.com/download.php?pid=847249&fid=9829834&key=362779"", header=T) And my last two questions (promise!): The first is related to the order of columns (ie. explanatory variables). I get different order of importance for my variables depending on their order in the training data. Is there a parameter I could fiddle with (e.g. ntree) to get a more stable importance order? And finally, since interactions are not implemented, is there another method I could use in R to find dependencies among categorical variables? (lm doesn't accept categorical variables).
