[R] bind select data frames

[Joshua Wiley]

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
