Create new data frame with conditional sums
Under the hood, sapply() is also a loop (at the interpreted level). As is lapply(), etc. -- Bert On Sun, Oct 15, 2023 at 2:34?AM Jason Stout, M.D. <jason.stout at duke.edu> wrote: > > That's very helpful and instructive, thank you! > > Jason Stout, MD, MHS > Box 102359-DUMC > Durham, NC 27710 > FAX 919-681-7494 > ________________________________ > From: John Fox <jfox at mcmaster.ca> > Sent: Saturday, October 14, 2023 10:13 AM > To: Jason Stout, M.D. <jason.stout at duke.edu> > Cc: r-help at r-project.org <r-help at r-project.org&gt...
