00:16:33 Daniel Adereti: do I have to run library(tidyverse) everytime I start my R?
00:17:15 Zaynaib Giwa, @zaynaib: You only need to call it once when you open R Studio
00:21:14 Shannon: To double check that you have it installed, you can click on the 'Packages' tab in the lower right pane. If it's installed, you'll see it listed next to a checkbox. Once you load the package with the library() function, you will see a checkmark in the box.
00:28:20 Freya Watkins (she/her): displ 's class is dbl (double) which is a floating point number for decimal precision. int (integer) is for full rounded values (I think)
00:28:49 Zaynaib Giwa, @zaynaib: cute cat
00:28:49 Vrinda Kalia: Yes, I was just typing that up @Freya I think you are right
00:30:26 Aalekhya Reddam: In Line 88 is it a - or = between data and mpg?
00:30:57 Matthew Efoli: I think it is an equal to sign
00:30:58 Aalekhya Reddam: Sorry that was my screen lagging!
00:38:43 Shannon: Another option for finding number of rows and number of columns, that I used, is nrow(mpg) and ncol(mpg). Not as much info as glimpse(), but more concise.
00:41:42 Freya Watkins (she/her): @Shannon, dim(mpg) also gives both dimensions in one command (number of rows, followed by number of columns) :)
00:42:35 Shannon: @Freya, perfect! thanks!
00:49:45 Zaynaib Giwa, @zaynaib: I have to leave a bit early. But it was nice meeting everyone. See you next week.
00:50:02 Shannon: See you next week!
00:50:30 Matthew Efoli: See you next week Zaynaib
00:50:34 Aalekhya Reddam: I have to head out too, see you all next week! :)
00:50:57 Shannon: 👋
00:51:06 Matthew Efoli: Have a nice weekend Aalekhya!
00:51:20 Freya Watkins (she/her): missing the closing bracket I think
00:53:58 Daniel Adereti: See you next week Aalekhya and Zaynaib!
00:54:27 Daniel Adereti: We have 10 more minutes, so we may have to carry over the chapter to next week, I think
00:55:10 Matthew Efoli: @Daniel okay
00:56:31 Shannon: That works for me. I'd have more time to look over the second half of the chapter. :)
00:56:52 Marielena Soilemezidi: Yes, same for me! :)
00:56:52 Vrinda Kalia: Yes, this sounds good to me as well!
00:59:17 Shannon: Nice work presenting, Adeyemi! Thank you!
00:59:20 Marielena Soilemezidi: Daniel, could you share the link of the spreadsheet here?
00:59:40 Daniel Adereti: https://docs.google.com/spreadsheets/d/1zy2nXNkvcdqWuF8rQ5ApWRkVQG_UJt0azu3h_mEnY2E/edit#gid=0
00:59:43 Marielena Soilemezidi: Because I couldn't find it in Slack for some reason
00:59:47 Marielena Soilemezidi: thank you!!
01:00:35 Daniel Adereti: 👍
01:08:40 Vrinda Kalia: Maybe try “stroke = class” ?
01:10:01 Freya Watkins (she/her): try stroke = 5. it should modify the width of the border so I think needs a numeric argument
01:10:08 Daniel Adereti: maybe this? ggplot(data = mpg)+
geom_point(mapping = aes(x = displ, y = hwy),
shape = 17,
stroke = 3)
01:10:32 Vrinda Kalia: I see, it needs a numeric argument
01:11:37 Vrinda Kalia: Thank you so much for leading the discussion, Adeyemi!
01:11:55 Matthew Efoli: Thank you so much Adeyemi!
01:11:56 Freya Watkins (she/her): Thank you, Adeyemi! Great job :)
01:11:57 anacuric: thank you!
01:11:58 Marielena Soilemezidi: Thank you guys! And thanks Adeyemi for presenting!! :)
01:12:00 Shannon: Thank you everyone!
01:12:01 Adeyemi Olusola: thank you
01:12:02 Marielena Soilemezidi: See you next week!
01:12:16 Matthew Efoli: see you next week!

00:06:29 Adeyemi Olusola: Good day Daniel
00:06:58 Daniel Adereti: Hello Olusola!
00:07:06 Daniel Adereti: Looking forward to today!
00:07:21 Adeyemi Olusola: Yeah yeah.
00:12:52 Amélie Gourdon-Kanhukamwe: Hi everyone, I am in my shared office at work, so cannot really speak (have been meaning to join from the start, but shared office = loads of distraction). (I am based in London UK).
00:14:12 Shannon: Hi Amelie, nice to 'meet' you :)
00:20:49 Aalekhya Reddam: I may have missed it but what is the difference between adding a period and not adding one for facet_grid?
00:22:41 Shannon: I think I missed that too, I second that question.
00:26:04 Freya Watkins (she/her): The point should have removed one of the dimensions - either vertical or horizontal
00:29:57 Shannon: So, having a point or no point would have the same result? Ex: ( ~ drv) is the same as( . ~drv)? Or (drv ~) is the same as (drv ~ .) ?
00:32:11 Aalekhya Reddam: That’s what I understood too Shannon! The location of the ~ determines orientation and I guess the “.” is a placeholder
00:32:48 Shannon: I think that's how I'm understanding it, too
00:39:09 Freya Watkins (she/her): Yes I believe that's right @Shannon, @Aalekhya - I think in the previous plot there was an extra dimension (drv ~ cyl) which had rows and columns, then replacing drv with a point (. ~ cyl) just returns a plot faceted with columns for cyl. Then (~ cyl) returns the same plot as (. ~ cyl)
00:39:44 Aalekhya Reddam: Ah okay, thank you Freya!
00:39:52 Shannon: Okay, thanks Freya!
00:58:00 Shannon: That last one drove me crazy, I couldn't figure it out! I tried position = jitter and tied to adjust stroke. Looks like the solution is two geom_point layers. Thanks for solving that one!
01:10:45 Aalekhya Reddam: I have another meeting and have to head out, thank you for a great lesson Adeyemi! See you all next week
01:10:57 Vrinda Kalia: Thank you so much, Adeyemi! I appreciate your thoroughness. I need to leave for a 1pm call. See you all next week!
01:11:06 Shannon: See you next week!
01:11:13 Daniel Adereti: Hello guys, will we like to conclude the chapter ourselves next time so we move to the next chapter with Matthew?
01:11:20 Shannon: Thank you Adeyemi!
01:11:30 Marielena Soilemezidi: See you guys! Thank you Adeyemi!!
01:11:32 Matthew Efoli: Thank you Adeyemi
01:11:35 Freya Watkins (she/her): Thanks Adeyemi! Really helpful, thanks for all the extra time and effort on the exercises
01:11:42 Amélie Gourdon-Kanhukamwe: Thank you!
01:11:58 Freya Watkins (she/her): I'm happy to finish the rest myself and move on to next chapter next time :)
01:12:43 Matthew Efoli: I have to go. I will be taking the next chapter
01:12:47 Freya Watkins (she/her): Bye! Thanks Daniel
01:12:52 Matthew Efoli: bye
