grep problem in R-devel 2.14 r57004
Problem below with PCRE grep in R-devel; works fine in R-patched. (Unless there's been an absolutely massive change in rules for updated PCRE version 8.13; jeez I hope not)

RCMD CHECK and non-methods

slow load() in R2.6.0
I'm encountering excruciatingly slow load times for character vectors in
R 2.6.0-- up to 30sec for a 15K file that contains a no-attributes
character vector of length ~1e4 and object size ~0.5MB. In R 2.5.1,
repeated loads of the same set of files are near-instantaneous.
The problem is proving tricky to reproduce consistently from scratch, so
I have attached the 3 files used in the examples

parse_Rd and/or lazyload problem
I'm encountering problems when making lazy-loadable databases of the output from 'parse_Rd'. The lazy-load database is of seemingly limitless size when I try to reload it... Admittedly I am using functions that I'm not really supposed to use, which is why this isn't a bug report, but there does seem to be something strange going on; my code is very similar to code that lives

sys.on.exit not working (PR#7665)

Bug with .First in R 2.10
Under R2.10.0 beta (2009-10-14 r50082) my .First does not run reliably. I reported this last week, but not reproducibly, and it seemed to go away, so I thought it might be installation-related. But it has now recurred reproducibly, at least on my machine.
The website ftp://ftp.csiro.au/MarkBravington contains two .RData files each containing (only) a .First. One of them does what it should, and

Hi all,
While dat['a1',] and dat['a10',] produce the same results in the

dat <- data.frame(x1 = paste(letters[1:5],10, sep=''), x2=rnorm(5))
rownames(dat) <- dat$x1

tcltk freezing using MS Windows for R-2.14+
I am the maintainer of a Bioconductor package (affylmGUI) which uses
tcltk. It freezes inconsistently on MS Windows, but not Mac or Unix. see
details below.
After considerable testing I have reduced the problem from a few
thousand lines of code to 30 lines!
If you paste the following lines of code into an R window:

I run R on MS Windows. In R2.9.0dev, I type ?base to get "R help for package

bnlearn and cpquery
Hi all
I have built a Bayesian network using discrete data using the bnlearn

When I try to run the cpquery function on this data it returns NaN for some
some cases.
Running the cpquery in debug mode for such a case (n=10^5, method="lw")
creates the following output:

I get the same style of path as Hadley. This is on Windows 7 Home Premium with SP1.
I start R by clicking on the R-2.31.0 icon.
I'd assumed that it was a change that came with R-2.13.0!
(On 32-bit Windows XP, which I have just checked, I do indeed get the 8.3 paths.)

R CMD SHLIB changes function name when compiling
Hi,
I'm trying to write a function in C for implementation with .Call. When
compiling using R CMD SHLIB characters seem to be added to the function
name.
Here's the complete C code from the file summariseMCMC.c:
#include<R.h>
#include<Rdefines.h>
#include<Rinternals.h>
void summariseMCMC(SEXP data) {
PROTECT(data=AS_NUMERIC(data));
UNPROTECT(1);
}
