R Documentation

Special Version of legend for R

Description

rlegend is a version of legend for R that implements plot=FALSE, adds grid=TRUE, and defaults lty, lwd, pch to NULL and checks for length>0 rather than missing(), so it's easier to deal with non-applicable parameters. But when grid is in effect, the preferred function to use is rlegendg, which calls the lattice draw.key function.

Usage

rlegend(x, y, legend, fill, col = "black", lty = NULL, lwd = NULL, pch = NULL, angle = NULL, density = NULL, bty = "o", bg = par("bg"), pt.bg = NA, cex = 1, xjust = 0, yjust = 1, x.intersp = 1, y.intersp = 1, adj = 0, text.width = NULL, merge = do.lines && has.pch, trace = FALSE, ncol = 1, horiz = FALSE, plot = TRUE, grid = FALSE, ...)

rlegendg(x, y, legend, col=pr$col[1], lty=NULL,
         lwd=NULL, pch=NULL, cex=pr$cex[1], other=NULL)

Arguments

`x`
`y`
`legend`
`fill`
`col`
`lty`
`lwd`
`pch`
`angle`
`density`
`bty`
`bg`
`pt.bg`
`cex`
`xjust`
`yjust`
`x.intersp`
`y.intersp`
`adj`
`text.width`
`merge`
`trace`
`ncol`
`horiz`	see `legend`
`plot`	set to `FALSE` to suppress drawing the legend. This is used the compute the size needed for when the legend is drawn with a later call to `rlegend`.
`grid`	set to `TRUE` if the `grid` package is in effect
`...`	see `legend`
`other`	a list containing other arguments to pass to `draw.key`. See the help file for `xyplot`.

Value

a list with elements rect and text. rect has elements w, h, left, top with size/position information.
