[R] Reducing the FPR (false positive rate)

Hello R-USERS,

I think some people didn't understand my question. What I want is to use the training set to minimize the FALSE POSITIVE RATE.

I think it is possible. I sacrifice ACCURACY to have less FALSE POSITIVES. I don't want a classifier result with 5% of FPR and, for example, 93% of ACCURACY. I want a 1% FPR sacrificing the 93% ACCURACY.

Do you know how can I do this? I really need this because the requisite of the work I'm doing is only 1% of FPR.

Thanks and best regards.
