extending lattice to S4 classes
Hi,
I'm writing methods for a package called FLCore (see
http://flr-project.org/) in particular for a class called "FLQuant"
which extends array.
Previously I was able to write methods based on the class of "data" but
now I can not do it due to the single parameter "x". Is there a way to
do this ?
Regards

How to get the names of the classes exported by a specific package.
Hi,
I'm writing some functions to generate Rd files for a S4 package. I want
to have 2 character vectors with the names of the S4 classes and the
methods exported by a package. To get the info about methods I'm using
"getGenerics(where="package:FLCore")" however I can not find a similar
process to get the S4 classes. Are there functions to access this
information

LinkingTo for 2 packages
Hello,
One of our packages contains C++ code that needs to be compiled against
2 other packages. So the LinkingTo field in DESCRIPTION looks like this
LinkingTo: FLCore,FLash
Both packages are also in the Depends field.
In R 2.6.2, first thing we noticed was that both names could not have
any space between them, althoguh the example in the html version of

Default argument value for "["
Dear all,
After installing R 2.4.0, a definition of "[" for an S4 class has
stopped working as the default for drop in the generic, TRUE, appears to

MATLAB vrs. R
I need to find the area under a trapezoid for a research-related project. I was able to find the area under the trapezoid in MATLAB using the code:

% user-defined quadrature function
% integrate data f from x=a to x=b assuming f is equally spaced over the interval

lattice histogram problem with integers values and nint
been puzzling over this for a day.
Summary
integer variable to use with histogram, 170,000 rows. Value is day of
year. Hist works, lattice histogram with nint does not work (spurious
spikes in display), lattice histogram using breaks=c(0:365) works
fine. Spike values appear to be sum of two adjacent bins. Want to
know if this is a familiar problem, and what the recommended
work-around is.

Trapezoid Rule
Dear R Users,
I've never used R before and my professor has asked us to do some
pretty intense programming (or it's intense to me at least). Here is
the question: Modify the function myquadrature inside the script so
that it returns the quadrature of descrete data using the trapezoidal
rule. Modify the call to the function at the bottom of the script so
that is uses your modifies

Lattice: arbitrary abline in multiple histograms
Dear list.
I have three histograms and I want to add a vertical abline in a different
place in each plot. The next example will plot a vertical line at x=5.5 in
the three plots:
rnorm(100,5,3) -> A
rnorm(100,7,3) -> B
rnorm(100,4,1) -> C
rep(c("A","B","C"),each=100) -> grp

Dropping 'empty' panels from lattice
I have 8 cofactors possibly affecting one and only one variable.
I make conditional histograms:

Quicken 2010 QDF file can't be read on windows machine
Hello,
I've been running Quicken 2010 under Wine for a while now. It works well, except that various elements redraw themselves over and over again, making it painfully slow to use.
Now for completely unrelated reasons I'm forced to run a Windows XP VM on my Linux machine, so I installed Quicken 2010 on the VM as well. When I copied my QDF file over from ~/.wine to the VM, though,
