Dear all, I would like to inquire, if it is a desired feature that the combination with rbind() of two data frames with factors columns does not sort the factors levels of the combined data frame. > str(rbind(data.frame(a = factor(c(4, 3))), data.frame(a = factor(c(2, 1))))) 'data.frame': 4 obs. of 1 variable: $ a: Factor w/ 4 levels "3","4","1","2": 2 1 4 3 I would expect the combined factor levels to be sorted, as long as both factors are not ordered. With many thanks and best regards, Stefan ____________________________________ Dr. Stefan Albrecht, CFA Allianz Private Equity Partners GmbH Königinstr. 19 | 80539 Munich | Germany
