I tried to recode some complex multiple variables and run into a problem that r can change only some column that I want to change. I can reproduce the problem with this idfortest <- c(6,23,46,63,200,238,297,321,336,364,386,392,414,434,441) id <- seq(1:500) id[id==idfortest] the result showed Warning in id == idfortest : longer object length is not a multiple of shorter object length [1] 200 386 434 can you enlighten me for this, thank you in advance.
