Examples
library("ggplot2")
library("ggthemes")
library("scales")
p <- ggplot(mtcars, aes(x = wt, y = mpg)) +
geom_point() +
ggtitle("Cars")
p2 <- ggplot(mtcars, aes(x = wt, y = mpg, colour = factor(gear))) +
geom_point() +
ggtitle("Cars")
p3 <- p2 + facet_wrap(~ am)Tufte theme and geoms
Minimal theme and geoms based on plots in The Visual Display of Quantitative Information.
p + geom_rangeframe() +
theme_tufte() +
scale_x_continuous(breaks = extended_range_breaks()(mtcars$wt)) +
scale_y_continuous(breaks = extended_range_breaks()(mtcars$mpg))
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
