facet_nested_wrap_color

R Documentation

Description

facet_nested_wrap_color behaves similarly to ggh4x::facet_nested_wrap() in that it wraps a sequence of panels onto a two-dimensional layout, and nests grouped facets where possible.. The main difference is that it also allows the user to specify the background and label colors of the individual facet strips using the colors and lab_colors arguments.

Usage

facet_nested_wrap_color(
  facets,
  nrow = NULL,
  ncol = NULL,
  scales = "fixed",
  axes = "margins",
  remove_labels = "none",
  shrink = TRUE,
  labeller = "label_value",
  colors = stages,
  lab_colors = "auto",
  as.table = TRUE,
  drop = TRUE,
  dir = "h",
  strip.position = "top",
  nest_line = element_line(inherit.blank = TRUE),
  solo_line = FALSE,
  resect = unit(0, "mm"),
  trim_blank = TRUE,
  strip = strip_nested(),
  bleed = NULL
)

Arguments

`facets`	A set of variables or expressions quoted by `vars()` and defining faceting groups on the rows or columns dimension. The variables can be named (the names are passed to `labeller`). For compatibility with the classic interface, can also be a formula or character vector. Use either a one sided formula, `~a + b`, or a character vector, `c("a", "b")`.
`nrow`, `ncol`	Number of rows and columns.
`scales`	A `character(1)` or `logical(1)` whether scales are shared across facets or allowed to vary. One of the following: `"fixed"` or `FALSE` Scales are shared across all facets (default). `"free_x"` x-scales are allowed to vary. `"free_y"` y-scales are allowed to vary. `"free"` or `TRUE` Both scales can vary
`axes`	A `character(1)` or `logical(1)` where axes should be drawn. One of the following: `"margins"` or `FALSE` Only draw axes at the outer margins (default). `"x"` Draw axes at the outer margins and all inner x-axes too. `"y"` Draw axes at the outer margins and all inner y-axes too. `"all"` or `TRUE` Draw the axes for every panel.
`remove_labels`	A `character(1)` or `logical(1)` determining whether axis text is displayed at inner panels. One of the following: `"none"` or `FALSE` Display axis text at all axes (default). `"x"` Display axis text at outer margins and all inner y-axes. `"y"` Display axis text at outer margins and all inner x-axes. `"all"` or `TRUE` Only display axis text at the outer margins.
`shrink`	If `TRUE`, will shrink scales to fit output of statistics, not raw data. If `FALSE`, will be range of raw data before statistical summary.
`labeller`	A function that takes one data frame of labels and returns a list or data frame of character vectors. Each input column corresponds to one factor. Thus there will be more than one with `vars(cyl, am)`. Each output column gets displayed as one separate line in the strip label. This function should inherit from the "labeller" S3 class for compatibility with `labeller()`. You can use different labeling functions for different kind of labels, for example use `label_parsed()` for formatting facet labels. `label_value()` is used by default, check it for more details and pointers to other options.
`colors`	Specifies which colors to use to replace the strip backgrounds. Either A) a function that returns a color for a given strip label, B) the character name of a function that does the same, C) a named character vector with names matching strip labels and values indicating the desired colors, or D) a data.frame representing a lookup table with columns named "name" (matching strip labels) and "color" (indicating desired colors). If the function returns `NA`, the default background color will be used.
`lab_colors`	Specifies which colors to use for the strip labels. Either A) a function that returns a color for a given strip label, B) the character name of a function that does the same, C) a named character vector with names matching strip labels and values indicating the desired colors, D) a data.frame representing a lookup table with columns named "name" (matching strip labels) and "lab_color" (indicating desired colors), or E) "auto" (the default), which set the labels to black or white, whichever has better contrast with the background color, based on recommendations by the International Telecommunication Union. If the function returns `NA`, the default label color will be used.
`as.table`	If `TRUE`, the default, the facets are laid out like a table with highest values at the bottom-right. If `FALSE`, the facets are laid out like a plot with the highest value at the top-right.
`drop`	If `TRUE`, the default, all factor levels not used in the data will automatically be dropped. If `FALSE`, all factor levels will be shown, regardless of whether or not they appear in the data.
`dir`	Direction: either `"h"` for horizontal, the default, or `"v"`, for vertical.
`strip.position`	By default, the labels are displayed on the top of the plot. Using `strip.position` it is possible to place the labels on either of the four sides by setting `strip.position = c("top", "bottom", "left", "right")`
`nest_line`	a theme element, either `element_blank()` or inheriting from `ggplot2::element_line()`. Lines are drawn between layers of strips indicating hierarchy. The element inherits from the `ggh4x.facet.nestline` element in the theme.
`solo_line`	A `logical(1)` indicating whether parent strips with a single child should be drawn with a `nest_line` (`TRUE`) or the line only applies to parents with multiple children (`FALSE`, default). Only relevant when `nest_line` is drawn.
`resect`	a `unit` vector of length 1, indicating how much the nesting line should be shortened.
`trim_blank`	A `logical(1)`. When `TRUE` (default), does not draw rows and columns containing no panels. When `FALSE`, the `nrow` and `ncol` arguments are taken literally, even when there are more than needed to fit all panels.
`strip`	An object created by a call to a strip function, such as `strip_nested()`.
`bleed`	the `bleed` argument has moved to the `strip_nested()` function.

Details

This function inherits the capabilities of facet_wrap2().

This function only merges strips in the same row or column as they appear through regular facet_wrap() layout behaviour.

Hierarchies are inferred from the order of variables supplied to facets. The first variable is interpreted to be the outermost variable, while the last variable is interpreted to be the innermost variable. They display order is always such that the outermost variable is placed the furthest away from the panels. For more information about the nesting of strips, please visit the documentation of strip_nested().

Examples

library(ggplot2)
df <- data.frame(x = 1:10, y = 1:10,
                 period = factor(c("Permian", "Triassic", "Jurassic",
                                   "Cretaceous", "Paleogene"),
                                 levels = c("Permian", "Triassic",
                                            "Jurassic", "Cretaceous",
                                            "Paleogene")),
                 era = factor(c("Paleozoic", "Mesozoic", "Mesozoic",
                                "Mesozoic", "Cenozoic"),
                                levels = c("Paleozoic", "Mesozoic",
                                           "Cenozoic")))
ggplot(df, aes(x, y)) +
  geom_point() +
  facet_nested_wrap_color(~ era + period, colors = rbind(periods, eras))
