# NOT RUN {
data(prgeng) # US Census engineer wage data 
xy <- prgeng[, c(1:4,6,5)] # Y value (wageinc here) must be last for polyFit() and FSR()
xy <- toFactors(xy, 2:4)  # convert education, occupation, and sex to factors
                          # (don't pass categorical variables as integer codes when fitting)
