Heya Folks, I've got to process a form that contains variable series of values, which i want to collect into a vectors. Say the first series has ten values, with id's ranging from X1 to X10, currently i process them in the following hardcoded manner: x1 <- c(as.numeric(POST$X1), as.numeric(POST$X2), as.numeric(POST$X3), as.numeric(POST$X4), as.numeric(POST$X5), as.numeric(POST$X6), as.numeric(POST$X7), as.numeric(POST$X8), as.numeric(POST$X9), as.numeric(POST$X10)) Is there a way to process these in a loop? Mazzel, Martijn.
