Hi,
set.seed(125)
dat1<-data.frame(BIRTHPLACE=sample(c("AG","AI","AR","BE","ZH","USA","GER","ESP"),20,replace=TRUE),RES_STA=sample(LETTERS[c(1:3,24:25)],20,replace=TRUE))
dat1$VARNEW<-ifelse(dat1$RES_STA=="X" & dat1$BIRTHPLACE%in%c("AG","AI","AR","BE","ZH"),"swiss","unknown")

Subject: [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!
David
