Hi, Here i have a data frame like this, frame name is "dat" *NAME AGE ELIGIBLE* A 20 B 14 C 35 D 10 E 50 In this, i want to change the column '*ELIGIBLE*' status to '*YES*' If, AGE between 18 to 35 Which means that, i should get a put like this... *NAME AGE ELIGIBLE* A 20 YES B 14 C 35 YES D 10 E 50 ---------------------------------------------- Now i got the solution for this, dat[dat$AGE<=35& da$AGE>18,"ELIGIBLE"]<-YES My issue is, i assigned AGE to a variable and that variable i tried inside the function. for eg:- *Obj_Name*<- AGE dat[dat$*Obj_Name*<=35& da$*Obj_Name*>18,"ELIGIBLE"]<-YES Now, what is i getting the error !.
You need dat[[Obj_Name]] rather than dat$Obj_Name, the latter means the same as dat[["Obj_Name"]] and hence is wrong. Uwe Ligges
So,could you please help me, what is the solution *pass column name through *variable to this function ? Can i get immediate solution please ? - Thanks Antony -- View this message in context: http://r.789695.n4.nabble.com/Use-variable-inside-Function-for-updating-the-matrix-tp4631663.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
