Extended grid facets

Description

This function behaves like ggplot2::facet_grid with default arguments, but has a few extra options. It can draw partial or full axis guides at inner panels, and position scales can be independent.

Usage

facet_grid2(
  rows = NULL,
  cols = NULL,
  scales = "fixed",
  space = "fixed",
  axes = "margins",
  remove_labels = "none",
  independent = "none",
  shrink = TRUE,
  labeller = "label_value",
  as.table = TRUE,
  switch = NULL,
  drop = TRUE,
  margins = FALSE,
  render_empty = TRUE,
  strip = strip_vanilla()
)

Arguments

`rows, cols`	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, `rows` can also be a formula with the rows (of the tabular display) on the LHS and the columns (of the tabular display) on the RHS; the dot in the formula is used to indicate there should be no faceting on this dimension (either row or column).
`scales`	A `character(1)` or `logical(1)` whether scales are shared across facets or allowed to vary. Interacts with the `independent` argument. One of the following: `"fixed"` or `FALSE` Scales are shared across all facets (default). `"free_x"` x-scales are allowed to vary across rows. `"free_y"` y-scales are allowed to vary across columns. `"free"` or `TRUE` Scales can vary across rows and columns.
`space`	A `character(1)` or `logical(1)` determining whether the size of panels are proportional to the length of the scales. When the `independent` argument allows for free scales in a dimension, the panel sizes cannot be proportional. Note that the `scales` argument must be free in the same dimension as the `space` argument to have an effect.One of the following: `"fixed"` or `FALSE` All panels have the same size (default). `"free_x"` Panel widths are proportional to the x-scales. `"free_y"` Panel heights are proportional to the y-scales. `"free"` or `TRUE` Both the widths and heights vary according to scales.
`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.
`independent`	A `character(1)` or `logical(1)` determining whether scales can vary within a row or column of panels, like they can be in ggplot2::facet_wrap. The `scales` argument must be free for the same dimension before they can be set to independent. One of the following: `"none"` or `FALSE` All y-scales should be fixed in a row and all x-scales are fixed in a column (default). `"x"` x-scales are allowed to vary within a column. `"y"` y-scales are allowed to vary within a row. `"all"` or `TRUE` Both x- and y-scales are allowed to vary within a column or row respectively.
`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.
`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.
`switch`	By default, the labels are displayed on the top and right of the plot. If `"x"`, the top labels will be displayed to the bottom. If `"y"`, the right-hand side labels will be displayed to the left. Can also be set to `"both"`.
`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.
`margins`	Either a logical value or a character vector. Margins are additional facets which contain all the data for each of the possible values of the faceting variables. If `FALSE`, no additional facets are included (the default). If `TRUE`, margins are included for all faceting variables. If specified as a character vector, it is the names of variables for which margins are to be created.
`render_empty`	A `logical(1)`: whether to draw panels without any data (`TRUE`, default) or display these as blanks (`FALSE`).
`strip`	An object created by a call to a strip function, such as `strip_vanilla`.

Details

Both the independent and space arguments only have an effect when the scales argument in a dimension is free. However, the independent and space arguments can not be used to simultaneously set an independent scale and have the panel size be proportional to that scale.

Value

A Facet ggproto object that can be added to a plot.

Examples

p <- ggplot(mpg, aes(displ, hwy)) + geom_point()

# Repeat all axes for every facet
p + facet_grid2(cyl ~ drv, axes = "all")

# Repeat only y-axes
p + facet_grid2(cyl ~  drv, axes = "y")

# Repeat axes without x-labels
p + facet_grid2(cyl ~ drv, axes = "all", remove_labels = "x")

# Grid facets with independent axes for every panel
p + facet_grid2(cyl ~ drv, scales = "free", independent = "all")
