I have encountered a strange behavior of the str function - it seems to
modify the object that is displayed. Probably I'm using something
unsupported (objects consisting just of an external reference), but
still I'm curious as of why this happens. I create (in C code)

Right. The NA is not important; foo[2] <- 1 crashes R just as

OK, I looked at the documentation and you're right about that. However,
I'm curious about why the first argument to UseMethod is ever necessary.
Is there ever a good reason for it to be something other than the name
of the calling function? (Wouldn't that lead to confusing code?) If
not, why bot

This bug has been fixed. It is not a bug specific to the R internals
but to the R.app version of the quartz device (R.app, i.e. the GUI,
embeds the R.framework, i.e. R 2.0.0 in your case).
You should look at http://www.economia.unimi.it/R to get the latest
build of R.app or to get instructions

Using plotmath produces text whose spacing is very wide. I used the provided
example
x <- seq(-4, 4, len = 101)
y <- cbind(sin(x), cos(x))
matplot(x, y, type = "l", xaxt = "n",

Is this not a bug in `vExplorer' (unexplained, but I believe in a BioC
package -- by no means all R users have any experience of BioC)?
Why change the docs to a limitation of some application not part of
core R?
I do wonder why you sent this to R-bugs and not to the maintainer of
vExplorer.

I recently wrote a vignette, with the following at the top of the .Rnw
file:
%%\VignetteIndexEntry{How to use look up tables for h() functions}
%%\VignetteDepends{sjedmin, spatstat}
Using vExplorer() on this function, I got an error from this part of
getVigInfo():
