Dear sir/madam,

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.

Regards,
Wisarut
