[R] Concatenating data frame

[Charles Cheung]

Hello, I have searched through the R-help archive and find that the easiest 
way to concatenate data records in a dataframe is to use rbind()


I know we can do that using rbind, but it is slow when we are doing rbind 
thousands of times to a growing list, each time adding one or two records to 
the ever growing existing data because in

existingRecords<-rbind(existingRecords, aNewRecordToBeAdded),

I am making a copy of the data each time rbind is called!

Is there a way to avoid these data copying?


Thank you in advance!
