00:10:24 Federica Gazzelloni: Hello!
00:10:31 Sandra Muroy: hi!

00:20:10 Jon Harmon (jonthegeek): https://smltar.com/ is the new book by Julia Silge and Emil Hvitfeldt.
00:20:42 Jon Harmon (jonthegeek): https://www.tidytextmining.com/ is the older Tidytext book by Julia Silge and David Robinson.
00:28:15 Njoki Njuki Lucy: do you also load the packages or that's sufficient for a readable code?
00:28:59 Jon Harmon (jonthegeek): Within an Rmd I tend to put a library() call per package at the top so it's easy to find, but in my exploration work I rarely library anything other than magrittr.
00:30:11 Njoki Njuki Lucy: okay, thank you
