00:08:43    Ryan Metcalf:   So sorry for my delay. Aerating the lawn! Fun!
00:10:36    Becki R. (she/her): Hello!
00:22:56    Becki R. (she/her): That's a good idea! It would be a nice reference.
00:24:30    Jon Harmon (jonthegeek):    https://cran.r-project.org/web/packages/DiagrammeR/index.html
00:24:33    Sandra Muroy:   diagramR?
00:25:12    Jon Harmon (jonthegeek):    I guess the sharable link is supposed to be: https://cran.r-project.org/package=DiagrammeR
00:26:06    Becki R. (she/her): That's a good reminder, thanks.
00:56:06    Ryan Metcalf:   Another way to notate Venn diagrams and/or discrete mathematics is to use LaTeX. This is not intended to deter you learning of R but may be useful when working with a larger team (especially DB admins!) https://www.purplemath.com/modules/venndiag2.htm
01:04:20    Jon Harmon (jonthegeek):    ggplot2::diamonds %>% dplyr::count(carat, cut, color, clarity, depth, table, price, x, y, z, sort = TRUE)
01:08:49    Ryan Metcalf:   Great Job Federica! Looking forward to next week!

00:22:57    Jon Harmon (jonthegeek):    Try this to see a quick example. You're right that the order of the columns is left then right either way, but the rows to keep changes.
band_members %>% left_join(band_instruments)
band_members %>% right_join(band_instruments)
00:29:17    Jon Harmon (jonthegeek):    band_instruments %>% left_join(band_members)
00:39:07    lucus w:    Seems like setdiff() is similar to dplyr::anti_join()… they maybe differ by how they prints?
00:40:45    Jon Harmon (jonthegeek):    anti_join only needs to match on one key column to exclude; setdiff is looking for the entire observations to be repeated.
00:41:29    lucus w:    Interesting.. thanks!
00:52:28    Njoki Njuki Lucy:   I don't understand what's happening exactly, if age is greater than 25, have it as 25L(int) otherwise its age?
00:53:56    Njoki Njuki Lucy:   okay, thanks
00:54:28    Federica Gazzelloni:    sorry my connection
01:05:28    Njoki Njuki Lucy:   thank you :)
01:05:33    lucus w:    Thanks y'all
