...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! Charles
