There appears to be a bug in the R xfig() driver. When I run a simple example, eg> data(InsectSprays) > boxplot(count ~ spray, data = InsectSprays, col = "lightgray")the boxplot is fine. Doing the same thing after> xfig(file='test.fig')and then opening in Xfig (ver3.2 patchlevel 2) on my Linux box produces boxplots where the boxes, although correctly shaded in, have lost the vertical line that defines the left edge of the box. That is, they look like | | | | ----- ----- | | | | instead of | | | | | ----- ----- | | | | This doesn't sound serious, but I'm running the result through pdf postprocessors (mpost, then ppower4), and the result comes out as triangles instead of boxes! A simple workaraound, I expect, would be to define the boxes as 5-point polygons rather than 4-point, to force closure (sorry if I'm not using the right jargon here). I tried to get a look at the boxplot code to check this out, but> boxplotjust produces function (x, ...) UseMethod("boxplot") Is there any way I can get at the boxplot code? Or is there another way out of my problem? I'd be very grateful for any help. I'll post this as a bug if this is confirmed. Thanks, Ted. Dr E.A.

XFig interprets it differently.> A simple workaraound, I expect, would be to define the boxes as > 5-point polygons rather than 4-point, to force closure (sorry if I'm > not using the right jargon here).Yes.> I tried to get a look at the boxplot code to check this out, but > > > boxplot > > just produces > > function (x, ...) > UseMethod("boxplot") > > Is there any way I can get at the boxplot code?

Hi,
Could I suggest that the documentation of "locator" and
"identify" be
modified so that they refer to each other and that the "graphic"
keyword be
added to "identify". If you think it's a good idea of course, I
would even
volunteer to do it if you can point me to the procedure. (What file(s) would
have to be modified beside Rd files if any and what do I do with them
afterward.)
I'm making this suggestion because I had a hard time locating them
especially "identify". I vaguely recalled the functionality was
implemented
but I had forgotten the function names. I got to "locator" using
help.search("graphic") and as for "identify" I had to
remember the name
which I finally did.
While writing this I took a look at some .Rd files, at keywords and at
keywords.db which are located in D:\R-1.2.0\doc of the main *nix source and
I wonder if there is any kind of information on how the help system works?
Thanks
