The function geom_tufteboxplot creates several variants of Tufte’s minimal-ink boxplots. For a boxplot with a point indicating the median, a gap indicating the interquartile range, and lines for whiskers:
p4 <- ggplot(mtcars, aes(factor(cyl), mpg))
p4 + theme_tufte(ticks=FALSE) + geom_tufteboxplot()
For a boxplot with an offset line indicating the interquartile range and a gap indicating the median:
p4 + theme_tufte(ticks=FALSE) +
geom_tufteboxplot(median.type = "line")
For a boxplot with an line indicating the interquartile range, a gap indicating the median, and points indicating the minimum and maximum:
p4 + theme_tufte(ticks=FALSE) +
geom_tufteboxplot(median.type = "line", whisker.type = 'point', hoffset = 0)
For a boxplot with a wide line indicating the interquartile range, a gap indicating the median, and lines indicating the minimum and maximum
p4 + theme_tufte(ticks=FALSE) +
geom_tufteboxplot(median.type = "line", whisker.type = 'line', hoffset = 0, width = 3)## Warning: position_dodge requires non-overlapping x intervals
