As far as I can see read.maimages is built on top of R's own
file-reading facilties, and they all read compressed (but not zipped)
files as from R 2.10.0.
So simply use
gzip -9 coral55?.spot
and rename the files back to *.spot.
If you need more compression, use xz -9e. (You can also do this
The inst/doc directory of the DAAG package has 6 files coral551.spot, ... that
are around 0.85 MB each. It would be useful to be able to zip then, but that
as matters stand interferes with the use of the Sweave file that uses them to
demonstrate input of expression array data that is in the "spot"
A minor gripe/request: Could all R CMD package tools not at the very
least be consistent in indicating when
they are done, as in
* DONE (packagename)
or at least
* DONE
R CMD build leaves one hanging, not knowing whether it has completed or
it is time to get another coffee.
* checking for fi

Then perhaps you needed to do your homework: the references on the
help page would have explained it to you.
Is there a way to close a connection without destroying it?

Thank you very much, gentlemen. It seems reference classes will make my life
much easier. I won't pretend that i fully understand the wizardry with
environments that you do, but it works :). Namely the steps to mtrace a
class method by doing what John and Mark outlined

I use Joshua's trick all the time. But it might still be nice with a
C implementation.
While we are discussing duplication, I would also like to see

Guess not, but you never know...

That's a nice solution for vectors. Unfortunately for me, I have a
matrix (which duplicated() handles by checking whole rows). So a better
example that I should have

I need a function which is similar to duplicated(), but instead of
returning TRUE/FALSE, returns indices of which element was duplicated.

Hi Andre,
1. Keep in mind that a S4 method belongs to a specific generic function,
not to a specific object or class. There is none such thing as a "class
member function" in the S4 system. As an example for illustration,
consider the following class definitions in Java:
class myClassA
{
int
21 matches
