The scatterplot uses points, but were we instead to draw lines we would get a line plot. If we used 【bars】, we’d get a bar plot. Neither of those examples makes sense for this data, but we could still draw them, as in Figure 3.2. In ggplot2 we can produce many plots that ...

The end points of the lines (aka whiskers) is at a distance of 1.5*IQR, where IQR or Inter Quartile Range is the distance between 25th and 75th percentiles. The points outside the whiskers are marked as dots and are normally considered as extreme points. Setting varwidth=T adjusts the ...
