Hi,
`model.matrix' might kill R with a segfault (on a illposed problem, but anyway):
mydf <- as.data.frame(sapply(1:40, function(i) gl(2, 100)))
f <- as.formula(paste("~ - 1 + ", paste(names(mydf), collapse = ":"), sep = ""))
X <- model.matrix(f, data = mydf)
*** caught segfault ***

I hope it isn't too late, I only came across this in a lecture this

Dear developeRs,
I thought that backslashes can be escaped in the usual way (and I think I
did this before) but I can't see why
R> gsub("\\", "x", "\alpha")
Error in gsub(pattern, replacement, x, ignore.case, extended, fixed,
useBytes) :
invalid regular expression '\'
gives an error.

Good morning again,
there is a second problem which keeps us from finishing new releases.
Package `kernlab' defines a `fit' S4 generic and `modeltools' does as
well (so this is kind of an internal communication problem). `party' and
`kernlab' define methods for `fit' and export them in their n
Good morning,
we recently observed a problem with importing S3 generics from a foreign
package (without namespace), defining a S3 method in a package _with_
namespace and the `cleanEx()' function which is automatically generated
and executed before examples are run by R CMD check.
