...BIC value). I have tried to do this in library(RcmdrPlugin.HH), and using the "leaps" code below. With the leaps code my problem is that my response is not a vector, it's a single value (density of a species) ANy help would be greatly appreciated. Thanks a lot, Kate ALL-SUBSETS REGRESSIOM DESCRIPTION leaps() performs an exhaustive search for the best subsets of the variables in x for predicting y in linear regression, using an efficient branch-and-bound algorithm. It is a compatibility wrapper for regsubsets [1] does the same thing better. Since the algorithm returns a best mode...

Hi, is there an easy way to get the calculated weights in a regression equation? for e.g. if my model has 2 variables 1 and 2 with coefficient .05 and .6 how can I get the computed values for a test dataset for each coefficient? data var1,var2 10,100 so I want to get .5, 60 back in a vector. This is a one row example but I would want to get a matrix of multiplied out coefficients
