position_dodgex: Dodge overlapping objects side-to-side which can be shifted...

In YuLab-SMU/ggtreeExtra: An R Package To Add Geometric Layers On Circular Or Other Layout Tree Of "ggtree"

Dodge overlapping objects side-to-side which can be shifted verically or horizontally.

Description

Dodging preserves the vertical position of an geom while adjusting the horizontal position. position_dodgex2 is a special case of position_dodgex for arranging box plots, which can have variable widths. position_dodgex2 also works with bars and rectangles. But unlike position_dodgex, position_dodgex2 works without a grouping variable in a layer.

Usage

position_dodgex(
  width = NULL,
  hexpand = NA,
  vexpand = NA,
  preserve = c("total", "single")
)

position_dodgex2(
  width = NULL,
  preserve = c("total", "single"),
  hexpand = NA,
  vexpand = NA,
  padding = 0.1,
  reverse = FALSE
)

Arguments

width	Dodging width, when different to the width of the individual elements. This is useful when you want to align narrow geoms with wider geoms.
hexpand	numeric, Horizon expand for geoms that have a position, default is NA.
vexpand	numeric, Vertical expand for geoms that have a position, default is NA.
preserve	Should dodging preserve the total width of all elements at a position, or the width of a single element?
padding	Padding between elements at the same position. Elements are shrunk by this proportion to allow space between them. Defaults to 0.1.
reverse	If TRUE, will reverse the default stacking order. This is useful if you're rotating both the plot and legend.

Examples

library(ggplot2)
library(patchwork)
iris$ID <- rep(c(rep("test1", 15), rep("test2", 15), rep("test3", 20)),3)
p <- ggplot(iris, aes(x=Species,y=Petal.Length,fill=ID))
p1 <- p + geom_bar(stat="identity",position=position_dodgex())
p2 <- p + geom_bar(stat="identity",position=position_dodgex(vexpand=5))
p3 <- ggplot(iris, aes(x=Petal.Length, y=Species, fill=ID)) +
      geom_bar(stat="identity", orientation="y",
               position=position_dodgex(hexpand=5))
p4 <- p1 + p2 + p3
p4
p5 <- p + geom_boxplot(position=position_dodgex2())
p6 <- p + geom_boxplot(position=position_dodgex2(vexpand=5))
p7 <- ggplot(iris, aes(x=Petal.Length, y=Species, fill=ID)) +
      geom_boxplot(orientation="y",
                   position=position_dodgex2(hexpand=5))
p8 <- p5 + p6 + p7
p8
