Piecharts at arbitrary position and radii.

`props`	a numeric vector giving the relations of the pie pieces (need not to be normalized).
`x`	x-position of the piechart.
`y`	y-position of the piechart.
`radius`	a numeric value giving the radius of the piechart.
`colpal`	a character vector containing R built-in color names or a name of a `LSD` colorpalette as a character string (see disco() or `disco`) (defaults to "heat", if not specified).
`simulate`	logical: if `TRUE` (`FALSE` by default), a converted colorpalette is used to simulate dichromat vision according to http://www.daltonize.org (see `daltonize`).
`daltonize`	logical: if `TRUE` (`FALSE` by default), a converted colorpalette is used to enhance dichromat vision according to http://www.daltonize.org (see `daltonize`).
`cvd`	character string implying the type of color vision deficiency ("p" for protanope, "d" for deuteranope or "t" for tritanope).
`edges`	an integer giving the number of edges the "circle" will have.
`add`	logical: if `TRUE` (`FALSE` by default), the pie is added to an existing plot.
`xlim`	x limits, standard graphics parameter.
`ylim`	y limits, standard graphics parameter.
`main`	title(s) of the plot, standard graphics parameter.
`alpha`	alpha value: a two-digit integer between 01 and 99 for color opacity, i.e. appearance of partial or full transparency (usage omitted by default).
`addPercent`	logical: if `TRUE` (`FALSE` by default), the percentage of each slice is written inside of the pie.
`textcol`	a R build-in color for the percentages of `addPercent`.
`clockwise`	if `TRUE` (`FALSE` by default), slices drawn clockwise (counter clockwise, if `FALSE`).
`init.angle`	a numerical value representing an angle as a starting angle for the drawn slices.
`labels`	a character vector giving the names for the pie slices.
`cex`	scaling a numeric value giving the expansion factor for the slice names (if labels are given).
`cex.percentage`	a numeric value giving the expansion factor for the percentage values (if `addPercent = TRUE`).
`border`	a R build-in color giving the border color (NA by default).
`...`	additional parameters to be passed to points and plot.
