Exercises for 2.2: Statistical graphics

Preliminaries

• load the `driving.Rdata` file.
• type `head( driving )` to look at the first few observations
• load the following packages: `lsr`
``````load( "~/Work/Research/Rbook/workshop_dsto/datasets/driving.Rdata")
``````##    id gender age distractor peak.hour errors_time1 errors_time2 rt_time1
## 1 s.1   male  19      radio       yes            7            7      346
## 2 s.2 female  42    toddler        no           15           16      424
## 3 s.3   male  27       none        no           10            7      415

##   rt_time2

Exercise 2.2.1: Scatter plot

• Draw as scatter plot of age (`age`) against RT on the first test (`rt_time1`)
• Customise the plot: give it a title, x-axis and y-axis labels, and maybe change the marker.

Solution 2.2.1:

``````plot(
x = driving\$age,
y = driving\$rt_time1,
)``````
