I see the printout (not an "error") that you describe on the 2nd example you gave:
> t2 <- WOETable(X=SFDC1$case_age, Y=SFDC1$survey) > print(t2) [1] GOODS BADS TOTAL PCT_G PCT_B WOE IV <0 rows> (or 0-length row.names) The result of WOETable is perfectly legal - it is a data.frame with no rows. help(WOETable) says that the 'X' argument should be a "categorical variable stored as factor" but the function does not check that that is true. You gave it a numeric (continuous) variable, case_age, and it misbehaved. You can turn case_age into a factor with the cut() function.
