Re: [R] stripchart with pch %in% 21:25 with bg
stripchart.formula() works for me with your modification to stripchart.default(). Great! But you don't need the 'bordered' pch for that. Indeed, but this may improve lisibility: # n - 500 x - rnorm(n) y - rnorm(n) fac1 - rep(c(male, female), n) fac2 - rep(c(blue, red), each = n/2) par(mfrow = c(1,2), lend = butt, mar = c(5,4,1,1), oma = c(0,0,4,0)) plot(x, y, pch = ifelse(fac1 == male, 15, 19), col = fac2, asp = 1) mbg - rgb(0.9, 0.9, 0.9, 0.9) legend(topleft, inset = 0.02, c(male,female), pch = c(15,19), bg = mbg) legend(bottomright, inset = 0.02, c(blue,red), col = c(blue,red), bg = mbg, lty = 1, lwd = 5) plot(x, y, pch = ifelse(fac1 == male, 22, 21), bg = fac2, asp = 1) legend(topleft, inset = 0.02, c(male,female), pch = c(22, 21), bg = mbg) legend(bottomright, inset = 0.02, c(blue,red), col = c(blue,red), bg = mbg, lty = 1, lwd = 5) mtext(Comparison of pch c(15, 19) versus c(22, 21), outer = TRUE, cex = 1.5, line = 1) ## Best, Jean -- Jean R.

Re: [R] stripchart with pch %in% 21:25 with bg
I think that it's a good idea, although I have rarely made use of pch 20. This reminds me to pass on a very belated thank-you to the developer(s) who implemented the formula version for stripchart, which I had promised to do myself quite a long time ago. Thanks, folks!

I found a simple workaround by redefining the function graphics:::stripchart.default() so that the dot-dot-dot (...) argument is forwarded the the function points(). I have also tried to source the code for striptchart.R in https://svn.r-project.org/R/trunk/src/library/graphics/R/stripchart.R with revision number 49800, but the output is unchanged. Am I missing something here? Is there no simpler way to achieve this goal? I have search the NEWS for stripchart and found only an entry for R 2.7.2 stating that: ostripchart() now passes '...' to title() (as well as to plot.default() and axis()). (Wish of PR#12202) I may send a wish to R-dev, but I would like to make sure before that I havn't miss something obvious.

Peter Ehlers Hi Peter, this is a good point by the way: my workaround is a shameless hack that does not handle the case of the graphics:::stripchart.formula(), while for sure it should. I hope that more competent people are going to have a look at this. The pch %in% 21:25 are very helpfull in some situations such as in a 2X2 contingency table : circles for women, squares for males, statisticians in blue, politicians in red (change for your favorite dichotomous credo here).
