I had a look at the source code and the coercion to double is only
done one the sum of each row/column, so the "overhead" (e.g. memory)
is only on the summed result. The integer matrix is *not*coerced to
double before summing, which could be case if done before calling the
native code. The latter
Hi,
there is one more thing to consider: the risk of getting integer
overflow. Should that be ignored? How is this handled by sum()?
I think it is good if {col|row}Sums() would return the same data type

Hi,
FYI, I just notice that on Windows (but not Linux) it is orders of
magnitude (below it's 50x) faster to serialize() and object to a
temporary file and then read it back, than to serialize to an object
directly. This has for instance impact on how fast digest::digest()
can provide a checksum.

how do I set options() when loading a package *without* a name space?
Is it possible?
I though this one was a common question, but I could not find it in

1.6.3 on "Load hooks" in "Writing R Extensions" says that this should

The reason why it "didn't work" was that I mispelled the option in

it is better to use "::" as below:
foo <- function(huge) {

Its possible that it is faster to serialize to a 'textConnection'.
However, it might be even faster if your internal code, i.e.

In the recent R-devel version, I receive the following error:

Hi,
I wish to return to the topic "[Rd] example(ask = .) - default ?"
discussed in R-devel on May 1, 2006, because I think it is related to
my problem.
In one of my Rd examples I generate multiple (20-30!) PNG files using
png()/dev.off(). I noticed that I get a "Hit to see next
plot:" for each

You can close the x11() device using dev.off() in your example. You
may also want to look at interactive() so you can test in your example
is the code is run interactively or not; the latter is the case for R
CMD check.

Hi. Far from complete, but some sketches on a solution is in the
Rdoc-to-Rd translator of the R.oo package. I, the author, never made
this very public because it uses a very ugly parser etc for it, but
the basics is there and I use it to generate \usage{} statements and
class hierarchies automati
Hi,
are there corresponding methods to exists() and get() where one can
stratify on class, e.g.
exists(..., inherits) instead of exists(..., mode)?
Thanks

Tried the following with R --vanilla on the Rv2.4.0 release (see
details at the end). I think the script and its comments speaks for
itself, but the outcome is certainly not wanted.
for (n in 58950:58970) {
cat("n=", n, "\n", sep="");
# Clean up first
rm(names, x, y); gc();
# Create a n
Thank *you* for identifying the source of the problem and fixing. :) /Henrik

I'm observing the following on different platforms:

expression("\177")

Error: invalid multibyte string

Error: invalid multibyte string
However,
cat("\x7F\n\x80\n...\xFF\n")
works. Using R --vanilla.

This is exactly what Peter pointed out in his example.

Hi Benilton,
it is possible that this has to do with so called unevaluated
promises. I had a similar problem a few months ago. I emailed R-devel
about it - "[Rd] save() saves extra stuff if object is not evaluated"
(Thu May
I use the R.oo Object class for what has been suggested previously.
The Object class can be thought of as utility wrapper class for
environments (actually environments gained much of its behavior some
time ago when "$" etc was being mapped to get() calls).
For caching to file, take a look at the R
