I am working with something like this : for (i in sel[-1]) { dd<-data.frame(do.call(rbind, mget(paste("DailyPL",i,sep=""),envir=.GlobalEnv)),row.names=NULL) }
But the result is not good. In the case where sel[-1]<-c("100420", "100421"), "dd" is only equal to "DailyPL100421" > -----Original Message----- > From: Joshua Wiley [mailto:jwiley.ps...@gmail.com] > Sent: Wednesday, June 02, 2010 4:48 PM > To: arnaud Gaboury > Cc: r-help@r-project.org > Subject: Re: [R] bind select data frames > > Hello, > > Does this do what you are looking for? > > ############ > output <- NULL > for(i in paste("DailyPL", sel, sep="")[-1]){ > output <- rbind(output, get(i)) > } > ############ > > If you just want to rbind all the data frames, there are ways of doing > it without a loop too, but since you specifically asked with the > condition for(i in sep[-1]) I did it using a loop. > > Best regards, > > Josh > > > On Wed, Jun 2, 2010 at 7:24 AM, arnaud Gaboury > <arnaud.gabo...@gmail.com> wrote: > > Dear group, > > > > Here is my environment: > > > >> ls() > > [1] "DailyPL100419" "DailyPL100420" "DailyPL100421" "dd" > "i" > > "l" "PLglobal" "Pos100416" "Pos100419" > "Pos100420" > > "Pos100421" "position" > > [13] "result" "sel" "Trad100416" "Trad100419" > > "Trad100420" "Trad100421" "trade" > > > > With "sel" the following element : > > > > sel <- > > c("100419", "100420", "100421") > > > > > > "DailyPL100419" , "DailyPL100420","DailyPL100421" are all data frames > with > > same columns names.
