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.
