Re: [R] memory problems when combining randomForests

I've just realised attachments are not allowed, so the data for the example in my previous message is:

pos.df=read.table("", header=T)

neg.df=read.table(""", 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).

Many thanks
