Geom_boxplot(aes(group = cut_width(carat, 0.25 )), outlier.alpha = 0.I'm trying to create some boxplots in R. # Adjust the transparency of outliers using outlier.alpha ggplot(diamonds, aes(carat, price)) + Geom_boxplot(aes(group = cut_width(carat, 0.25 ))) cut_width is particularly useful ggplot(diamonds, aes(carat, price)) + # You can also use boxplots with continuous x, as long as you supply # a grouping variable. # Boxplots are automatically dodged when any aesthetic is a factor p + geom_boxplot(aes(colour = drv)) # Remove outliers when overlaying boxplot with original data points p + geom_boxplot(outlier.shape = NA ) + geom_jitter(width = 0.2 ) Use # lour to override p + geom_boxplot(lour = 'red', outlier.shape = 1 ) # By default, outlier points match the colour of the box. P + geom_boxplot(fill = 'white', colour = '#3366FF' ) # Orientation follows the discrete axis ggplot(mpg, aes(hwy, class )) + geom_boxplot() Length of the whiskers as multiple of IQR. Use to override the default connection between That define both data and aesthetics and shouldn't inherit behaviour from If FALSE, overrides the default aesthetics, It can also be a named logical vector to finely select the aesthetics to NA, the default, includes if any aesthetics are mapped.įALSE never includes, and TRUE always includes. Should this layer be included in the legends?

See the Orientation section for more detail. Rare event that this fails it can be given explicitly by setting orientation The default ( NA)Īutomatically determines the orientation from the aesthetic mapping. If TRUE, missing values are silently removed. If FALSE, the default, missing values are removed withĪ warning. Square-roots of the number of observations in the groups (possibly TRUE, boxes are drawn with widths proportional to the If the notches of two boxes do not overlap, this suggests that the mediansįor a notched box plot, width of the notch relative to If FALSE (default) make a standard box plot. Same with outliers shown and outliers hidden. It only hides them, so the range calculated for the y-axis will be the Importantly, this does not remove the outliers, Hiding the outliers can be achievedīy setting outlier.shape = NA. The raw data points on top of the boxplot. Sometimes it can be useful to hide the outliers, for example when overlaying In the unlikely event you specify both US and UK spellings of colour, the lour, lor, outlier.fill, outlier.shape, outlier.size, outlier.stroke, outlier.alphaĭefault aesthetics for outliers. Often aesthetics, used to set an aesthetic to a fixed value, likeĬolour = 'red' or size = 3. 'jitter' to use position_jitter), or the result of a call to a Position adjustment, either as a string naming the adjustment Seeįortify() for which variables will be created.Ī function will be called with a single argument, All objects will be fortified to produce a data frame.

If NULL, the default, the data is inherited from the plotĭata as specified in the call to ggplot().Ī ame, or other object, will override the plotĭata. You must supply mapping if there is no plot Inherit.aes = TRUE (the default), it is combined with the default mappingĪt the top level of the plot. Set of aesthetic mappings created by aes().
