Dear R helpers,

I'm trying to build logistic regression model large dataset 360 factors and
850 observations. All 360 factors are known to be good predictors of outcome
variable but I have to find best model with maximum 10 factors. I tried to
fit full model and use stepAIC function to get best model but unfortenatly,
the process takes too long to complete (more than 4 hours)...

Is it expected behaviour of stepAIC function from MASS package or I'm doing
something wrong.

Any suggestions?

Thanks
