geom_stripped_rows

Alternating Background Colour

Description

Add alternating background color along the y-axis. The geom takes default aesthetics odd and even that receive color codes.

Usage

geom_stripped_rows(
  mapping = NULL,
  data = NULL,
  stat = "identity",
  position = "identity",
  ...,
  show.legend = NA,
  inherit.aes = TRUE,
  xfrom = -Inf,
  xto = Inf,
  width = 1,
  nudge_y = 0
)

geom_stripped_cols(
  mapping = NULL,
  data = NULL,
  stat = "identity",
  position = "identity",
  ...,
  show.legend = NA,
  inherit.aes = TRUE,
  yfrom = -Inf,
  yto = Inf,
  width = 1,
  nudge_x = 0
)

Arguments

`mapping`	Set of aesthetic mappings created by `aes()` or `aes_()`. If specified and `inherit.aes = TRUE` (the default), it is combined with the default mapping at the top level of the plot. You must supply `mapping` if there is no plot mapping.
`data`	The data to be displayed in this layer. There are three options: If `NULL`, the default, the data is inherited from the plot data as specified in the call to `ggplot()`. A `data.frame`, or other object, will override the plot data. All objects will be fortified to produce a data frame. See `fortify()` for which variables will be created. A `function` will be called with a single argument, the plot data. The return value must be a `data.frame`, and will be used as the layer data. A `function` can be created from a `formula` (e.g. `~ head(.x, 10)`).
`stat`	The statistical transformation to use on the data for this layer, as a string.
`position`	Position adjustment, either as a string, or the result of a call to a position adjustment function.
`...`	Other arguments passed on to `layer()`. These are often aesthetics, used to set an aesthetic to a fixed value, like `colour = "red"` or `size = 3`. They may also be parameters to the paired geom/stat.
`show.legend`	logical. Should this layer be included in the legends? `NA`, the default, includes if any aesthetics are mapped. `FALSE` never includes, and `TRUE` always includes. It can also be a named logical vector to finely select the aesthetics to display.
`inherit.aes`	If `FALSE`, overrides the default aesthetics, rather than combining with them. This is most useful for helper functions that define both data and aesthetics and shouldn't inherit behaviour from the default plot specification, e.g. `borders()`.
`xfrom, xto`	limitation of the strips along the x-axis
`width`	width of the strips
`yfrom, yto`	limitation of the strips along the y-axis
`nudge_x, nudge_y`	horizontal or vertical adjustment to nudge strips by

Examples

# Small function to display plots only if it's interactive
p_ <- GGally::print_if_interactive

data(tips, package = "reshape")
p <- ggplot(tips) +
  aes(x = time, y = day) +
  geom_count() +
  theme_light()

p_(p)
p_(p + geom_stripped_rows())
p_(p + geom_stripped_cols())
p_(p + geom_stripped_rows() + geom_stripped_cols())

p <- ggplot(tips) +
  aes(x = total_bill, y = day) +
  geom_count() +
  theme_light()
p
p_(p + geom_stripped_rows())
p_(p + geom_stripped_rows() + scale_y_discrete(expand = expansion(0, 0.5)))
p_(p + geom_stripped_rows(xfrom = 10, xto = 35))
p_(p + geom_stripped_rows(odd = "blue", even = "yellow"))
p_(p + geom_stripped_rows(odd = "blue", even = "yellow", alpha = .1))
p_(p + geom_stripped_rows(odd = "#00FF0022", even = "#FF000022"))

p_(p + geom_stripped_cols())
p_(p + geom_stripped_cols(width = 10))
p_(p + geom_stripped_cols(width = 10, nudge_x = 5))
