In the questions below, use R code to answer questions. For any non-coding questions, give your answer as a comment.

Run this code chunk first, to make the data set from the code along is available as the variable sick:

library(tidyverse)
── Attaching core tidyverse packages ──────────────────────── tidyverse 2.0.0 ──
✔ dplyr     1.1.4     ✔ readr     2.1.5
✔ forcats   1.0.0     ✔ stringr   1.5.1
✔ ggplot2   3.5.1     ✔ tibble    3.2.1
✔ lubridate 1.9.3     ✔ tidyr     1.3.1
✔ purrr     1.0.2     
── Conflicts ────────────────────────────────────────── tidyverse_conflicts() ──
✖ dplyr::filter() masks stats::filter()
✖ dplyr::lag()    masks stats::lag()
ℹ Use the conflicted package (<http://conflicted.r-lib.org/>) to force all conflicts to become errors
sick<-read_csv("sick_data.csv")
Rows: 349 Columns: 10
── Column specification ────────────────────────────────────────────────────────
Delimiter: ","
chr (4): last, first, sex, specialties
dbl (6): age, height_cm, weight_kg, perc_fish, perc_plant, doctor_trips

ℹ Use `spec()` to retrieve the full column specification for this data.
ℹ Specify the column types or set `show_col_types = FALSE` to quiet this message.
  1. What does “gg” in “ggplot” stand for? What are the three components of data visualizations?
  1. Create a histogram of the distribution of team member weights with ggplot. Make sure you add descriptive labels.
  1. Create a scatter plot displaying participant weight with percent plant intake using ggplot. Label axes appropriately.
  1. Describe why you might use a histogram, scatter plot, or bar plot (i.e. what is the purpose of each?).
  1. Generate a bar plot showing the average fish consumption among those who specialize in Management, Genetics, and Medicine. Include labels, and use the “fill” attribute to generate colors and a legend.
  1. For each of the three plots above, write code to save the files to “histogram.jpg”, “scatterplot.jpg”, and “barplot.jpg”. (Hint: assign each plot to a variable as part of your answer)
