...and assign a 'O' if values on any variable which have a value <= 0. The outcome of this code is to assign a single 'O'. Clearly I have made a mistake somewhere. pre_ <- new <- rep(0, nrow(reoffend)) > pre_ <- new[reoffend$pre01111 | reoffend$pre012 | reoffend$pre013>= 1] <-'V' > pre_ <- new[reoffend$pre02111>=1 | reoffend$pre02114>=1 | reoffend$pre2029>=1 | reoffend$pre0212>=1 | reoffend$pre0211>=1]<- 'V' > pre_ <- new[reoffend$pre03a >=1 | reoffend$pre0311 >=1 | reoffend$pre0312 >=1| reoffend$...

I was hoping for some advice regarding indexing, From a dataframe there are 27 variables of interest, with the prefix of "pre". [7] "Decision" "MHCDate" "pre01" "pre01111" "pre012" "pre013" [13] "pre02" "pre02111" "pre02114" "pre0211" "pre0212" "pre029" [19] "pre03a" "pre0311" "pre0312" "pre03" "pre04" "pre05" [25] "pre06"...
