R devel - Sep 2009 - Wish for stripchart to handle pch %in% 21:25 with bg

Dear R-Devel,

consider :

###
x <- round(rnorm(50))
stripchart(x,  pch = 21, col = "black", bg = "pink", method
= "jitter")
points(0.5, 1, pch = 21, col = "black", bg = "pink", cex =
2)
###

Under R 2.9.0 the internal color of the single point produced by points()
was honored but not the color of the points produced by stripchart().

My wish is just that the "bg" parameter for internal point color
should not be lost by the stripchart() function.

This looks somewhat similar for the entry in NEWS for R 2.7.2 stating
that:

     o	stripchart() now passes '...' to title() (as well as to
	plot.default() and axis()). (Wish of PR#12202)

A simple fix that works for me is to forward the argument ... to
the function points() in graphics:::stripchart.default(), but I
know nothing about potential side effects.

Thanks for your amazing work,

Pr. Jean Lobry
