Hello,
I wish to carry out the following: factor_classes <- as.factor(sample(c("BM", "SM", "F"), 10, replace = TRUE)) C <- 5 k <- matrix(0, length(factor_classes), 1) for (i in length(factor_classes)) { k[i] <- C*factor_classes[i] } I get the following error message: non-numeric argument to binary operator I wish to store the results of C*factor_classes[i] in matrix k. Is there any way I can multiply the factor with the numeric variable? Thanks for your help in advance. Cheers, sumaria [[alternative HTML version deleted]]
