| tisLegend {tis} | R Documentation |
The plotting functions tisPlot and
scatterPlot leave an object named latestPlot in the
frame from which they were called. tisLegend uses that object
to set legend arguments (which you can override) and sets reasonable
defaults for other arguments.
tisLegend(..., xrel = 0.1, yrel = 0.1, xjust = 0, yjust = 1, boxType = "n", ncol = 1, cex = 1)
... |
optional arguments to be passed on to legend.
These can include x and y arguments to position the
legend, or a list with components named x and y, such as
the list returned by locator(1). |
xrel, yrel |
Optional numbers between 0 and 1 to specify placement relative to the boundaries of the plot. |
xjust, yjust, ncol |
passed along to legend |
boxType |
passed along as bty to legend |
cex |
gets multiplied by the cex from latestPlot
and then passed on to legend |
This function is not strictly necessary, in that you could just
call legend directly. tisLegend makes things a
bit easier, however, by using the same argument names as
tisPlot and scatterPlot to specify color,
lineType, plotChar and boxType, rather than the
less intuitive col, lty, pch and bty
names. The xrel and yrel arguments provide an
alternative way to specify legend placement, one that is used by the
ChartMaker program.
