Default Panel Function for xyplot

Description

This is the default panel function for xyplot. Also see panel.superpose. The default panel functions for splom and qqmath are essentially the same function.

Usage

panel.xyplot(x, y, type="p",
             pch = plot.symbol$pch,
             col,
             col.line = plot.line$col,
             col.symbol = plot.symbol$col,
             font = plot.symbol$font,
             fontfamily = plot.symbol$fontfamily,
             fontface = plot.symbol$fontface,
             lty = plot.line$lty,
             cex = plot.symbol$cex,
             lwd = plot.line$lwd, ...)
panel.splom(...)
panel.qqmath(...)
panel.qq(...)

Arguments

`x,y`	variables to be plotted in the scatterplot
`type`	character vector consisting of one or more of the following: `"p", "l", "h", "b", "o", "s", "S", "r", "smooth"`. The behaviour if any of the first six are included in `type` is similar to the effect of `type` in `plot`. `"r"` adds a regression line (same as `panel.lmline`, except for default graphical parameters), and `"smooth"` adds a lowess fit (same as `panel.loess`). See example in `xyplot` for an example.
`col, col.line, col.symbol`	default colours are obtained from `plot.symbol` and `plot.line` using `trellis.par.get`.
`font, fontface, fontfamily`	font used when `pch` is a character
`pch, lty, cex, lwd`	other graphical parameters.
`...`	extra arguments, if any, for `panel.xyplot`. In most cases `panel.xyplot` ignores these. For types "r" and "smooth", these are passed on to `panel.lmline` and `panel.loess` respectively.

Details

Creates scatterplot of x and y, with various modifications possible via the type argument. panel.qq draws a 45 degree line before calling panel.xyplot.

Note that most of the arguments controlling the display can be supplied directly to the high-level xyplot call.
