Re: [R] dplyr : row total for all groups in dplyr summarise

Yes. But in the sample code the data is summarised. In which case you get 4 rows and not the correct 32. On Tue, 5 Jul 2016, 07:48 David Winsemius, wrote: > nrow(mtcars) > > > Sent from my iPhone > > On Jul 4, 2016, at 9:03 PM, Ulrik Stervbo wrote: > > That will give you the wrong result when u
