[R] recoding variables again :(
Hello everybody! I have again a rather simple question concerning recoding of variables: I have a variable/data-frame column BIRTHPLACE containing abbreviations of the 26 swiss counties (AG, AI, AR, BE, ZH, ... ) as well as international country codes (USA, GER, ESP, etc.) and another variable RES_STA indicating the residence status (A, B, C, X, Y) My goal is now to create a new variable VARNEW under the following conditions: - should be the RESIDENCE_STATUS - except: - if RESIDENCE_STATUS is X and at the same time BIRTHPLACE is one of the 26 swiss counties then it should be swiss - otherweise it should be unknown I have already tried the following code: mydata$VARNEW-mydata$RESIDENCE_STATUS # setting VARNEW as RESIDENCE_STATUS idx-(mydata$RESIDENCE_STATUS==X !(# TRUE: unknown; FALSE: swiss mydata$BIRTHPLACE==AG | mydata$BIRTHPLACE==BE | mydata$BIRTHPLACE==AR ... ) ) and then? Thank you for any help!
