You have 5 minutes for this activity.

Read the following code chunks out loud. As a group, try to come to an agreement on how to pronounce everything you see on the screen.

library(palmerpenguins)

aggregate(penguins[, 3], list(penguins$species), median, na.rm = TRUE)

##     Group.1 bill_length_mm
## 1    Adelie          38.80
## 2 Chinstrap          49.55
## 3    Gentoo          47.30

library(palmerpenguins)
library(dplyr)

penguins %>%
  group_by(species) %>%
  summarise(median_bl = median(bill_length_mm, na.rm = TRUE))

##  [90m# A tibble: 3 x 2 [39m
##   species   median_bl
##  [90m* [39m  [3m [90m<fct> [39m [23m          [3m [90m<dbl> [39m [23m
##  [90m1 [39m Adelie         38.8
##  [90m2 [39m Chinstrap      49.6
##  [90m3 [39m Gentoo         47.3

Think back to when you first started learning R… What is an R (or general programming) related term that wasn’t clear to you but your instructor, book, documentation, etc. assumed familiarity with it?
