Data visualization, part 1. Code for Quiz 7
1.Load the R package we will use.
-Create a plot with the faithful dataset -add points with geom_point -assign the variable eruptions to the x-axis -assign the variable waiting to the y-axis -colour the points according to whether waiting is smaller or greater than 76
-Create a plot with the faithful data set -use geom_histogram() to plot the distribution of waiting time -assign the variable waiting to the x-axis
-See how shapes and sizes of points can be specified here
-Create a plot with the faithful dataset
-add points with geom_point
-assign the variable eruptions to the x-axis -assign the variable waiting to the y-axis -set the shape of the points to SEE QUIZ -set the point size to SEE QUIZ -set the point transparency SEE QUIZ-Create a plot with the faithful dataset -use geom_histogram() to plot the distribution of the eruptions (time) -fill in the histogram based on whether eruptions are greater than or less than 3.2 minutes
-Create a plot with the mpg dataset -add geom_bar() to create a bar chart of the variable manufacturer
-change code to count and to plot the variable manufacturer instead of class
-change code to plot bar chart of each manufacturer as a percent of total -change class to manufacturer
-For reference see examples.
-Use stat_summary() to add a dot SEE QUIZ at the median of each group
-color the dot SEE QUIZ
-make the shape of the dot SEE QUIZ
-make the dot size SEE QUIZ
