geom_Xline

Fixed Value Lines

Description

Plot fixed value lines, for the top, left and right axis, analagous to the geom_hline and geom_vline geometries in ggplot2

Usage

geom_Tline(mapping = NULL, data = NULL, ..., Tintercept,
  na.rm = FALSE, show.legend = NA)

Tline(mapping = NULL, data = NULL, ..., Tintercept, na.rm = FALSE,
  show.legend = NA)

tline(mapping = NULL, data = NULL, ..., Tintercept, na.rm = FALSE,
  show.legend = NA)

geom_Lline(mapping = NULL, data = NULL, ..., Lintercept,
  na.rm = FALSE, show.legend = NA)

Lline(mapping = NULL, data = NULL, ..., Lintercept, na.rm = FALSE,
  show.legend = NA)

lline(mapping = NULL, data = NULL, ..., Lintercept, na.rm = FALSE,
  show.legend = NA)

geom_Rline(mapping = NULL, data = NULL, ..., Rintercept,
  na.rm = FALSE, show.legend = NA)

Rline(mapping = NULL, data = NULL, ..., Rintercept, na.rm = FALSE,
  show.legend = NA)

rline(mapping = NULL, data = NULL, ..., Rintercept, na.rm = FALSE,
  show.legend = NA)

Arguments

`mapping`	Set of aesthetic mappings created by `aes()` or `aes_()`.
`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)`).
`...`	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.
`Tintercept, Lintercept, Rintercept`	the intercepts for the T, L and R axis respectively
`na.rm`	If `FALSE`, the default, missing values are removed with a warning. If `TRUE`, missing values are silently removed.
`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.
