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!
