I'm also interested in finding out what I can do in R and which methods will allow prediction. Can anybody point me to a citation or discussion? Specifically, I want to classify remotely sensed imagery where training data is extracted on class membership by the user.

Hi, I am very new to R and cannot seem to find how it generates random numbers. I am currently involved with a project that requires a random number generator and have developed one.

If anyone knows how the random numbers are generated or have any ideas on testing or

Hi all, I would like to preform an autologistic regression analysis on my thesis data. This is a form of logistic regression that accounts for spatial autocorrelation within and between predictor variables.

Hi, I have a function foo(x,y) and a dataframe, DF, comprised of two vectors, x & w, as follows : x w 1 1 1 2 2 1 3 3 1 4 4 1 etc I would like to apply the function foo to each 'pair' within DF e.g foo(1,1), foo(2,1), foo(3,1) etc I have tried >apply(DF,foo) >apply(DF[,],foo) >apply(DF[DF$x,DF$w],foo) However, none of the above worked.

I suspect my problem is similar to having an order and wanting to have order items as part of the order, so I''ll explain the problem in those more familiar terms and then explain what if anything makes my actual situation different at the end.
