Thank you Sarah!! My data frame is b and I have to remove from column anslogin every value from vector quit
b= ht dispsplit anslogin month_ 1038 162 4627 1 475 1 4305 1 205 103 4136 1 296 1 4627 1 784 9 51274 1 451 75 4593 1 quit= 4079 4081 4095 4096 4119 4134 So, i should do b[!(b$ansologin%in%quit),], right? How does the %in% work??? Is it a normal in and the not comes with the ! ate the beggining? I have never used it, so thanks for teaching me this!.
