Pointer position on keypress event?
Hi.
Is there any straightforward way to tell pointer position (x, y)
upon keypress? In original wxWidgets, wxKeyEvent supports GetX()
and GetY() methods, but wxRuby''s KeyEvent object does not have
one. I also checked with event.methods and event.instance_variables.
Do I need to keep track of pointer position by evt_motion?

R.oo: do work on data member at construction
Hello,
I'd like to 'do work' on data members upon construction (i.e. without
implementing it in a get method). Is this the best way to create data member
'z' upon construction? I'm thinking if .z=paste(x,y) below gets more complex
I'll run into issues.
setConstructorS3("MyClass", function(x=NA,y=NA,...) {
this <- extend(Object(), "MyClass",

mouse position without event
Hello,
Is it possible somehow to get mouse coordinates without using the event
mechanism ?
I need to get the current mouse position to initialize some div position,
but not at page load

package.skeleton() in R-2.4.1
Hi
R version 2.4.0 alpha (2006-09-06 r39158)
MacOSX 10.4.7
There was a thread some time ago as to whether the structure created by
package.skeleton() would pass R CMD check.
I have an example where package.skeleton() gives an R file that gives an
error when sourced.
If I type

How to reduce key strokes when defining S4 classes?
I feel tedious when I define a S4 class and the methods. For each
method, I have to call both setMethod and setGeneric (or both
setReplaceMethod and setGeneric). I would like a more compact grammar
so that I can reduce the key strokes. I'm wondering if there is a
better way available.
setClass(
Class='A',
representation=representation(
x='numeric'
)

Patch to wxMouseEvent.h
This patch just applies some const tags that were missing (does this
affect anything at all?) and removes a definition that was causing a
conflict.

R.oo data members / inheritance
If someone is able, can you tell me if there is a better way to do this?
More specifically, do I have to rewrite all of the data members stuff and
extend stuff of parent class in the child class? See below. Thanks in
advance!
Example 1:
setConstructorS3("ClassA", function(A,x) {
if(missing(A))A=15;
if(missing(x))x=NA;
extend(Object(), "ClassA",
.size = A,
.x=x

NAMESPACE problems
Hi.
I am having difficulty following section 1.6.6 of the R-extensions manual.
I am trying to update the Brobdingnag package to include a NAMESPACE file (the
untb package requires the Brobdingnag package).
Without the NAMESPACE file, the package passes R CMD check cleanly.
However, if I include a NAMESPACE file, even an empty one, R CMD check
gives the following error in 00install.out:

RGtk2 - retrieve ggraphics mouse coordinates during drag-and-drop event

I have a gtable and a ggraphic widget.
I want to drag an element from the table onto the graphic.
When the drag object is released over the ggraphic widget, I want the
mouse coordinates inside the ggraphic to be returned.
Right now I do not know how to get the mouse ccordinates of the
ggraphic widget at any given time.
How can I access the ggraphics mouse coordinates?

Dear friends - I'm having troubles with nlme fitting a simplified model
as shown below eliciting the error
Error in chol.default((value + t(value))/2) :

I have seen the threads on this error but it didn't help me solve the
problem.
The model runs well in brms and identifies the used parameters even with
fixed effects for TRT?

what is the preferred method to create a package local variable?
for the moment, I'm using:
.onAttach <- function(libname, pkgname) {
.bbg.db.conn <<- dbConnect(dbDriver("PostgreSQL"), user="blah","blah")
}
.onUnload <- function(libpath) {
dbDisconnect(.bbg.db.conn)
}
which results in a hidden global variable in the global environment.
I would prefer to make the assignment only in the package namespace.

transforming output of grid.locator() to coordinates of a leaf viewport

How do I transform the output of grid.locator() (or

Thanks in advance. -Ben

I would like the user to be able to click anywhere on the R

R.oo package: do setMethodS3 work upon construction
Hello (Heinrich),
I did not know I could do this. It doesn't seem to be documented anywhere.
Thought this would be helpful to the fraction of the community using package
R.oo. Note the call of a setMethodS3 method, xOne, in the setConstructorS3.
This is extremely useful if xOne (in this case) is a very complex method
(that you always want to be called every time you create a new object). If I

[LLVMdev] Unexpected spilling of vector register during lane extraction on some x86_64 targets
Hello,
Depending on how I extract integer lanes from an x86_64 xmm register, the
backend may spill that register in order to load scalars. The effect was
observed on two targets: corei7-avx and btver1 (I haven't checked other
targets).
Here's a test case with spilling/no-spilling code put on conditional
compile:

Less aggressive on the first allocation of CSR if detecting an early exit
When compiling C code below for AArach64, I saw that shrink-wrapping didn't
happen due to the very early uses of CSRs in the entry block. So CSR
spills/reloads are executed even when the early exit block is taken.
int getI(int i);
int foo(int *P, int i) {
if (i>0)
return P[i];
i = getI(i);
return P[i];
}

Local Moran's I / Getis and Ord and Rousseauw Cluster Algorithms
Sorry for the repetition, unless I've got bad deja vu this questions been
asked before but I couldn't turn up an answer on CRAN. Is there already
any code in existence for local dependence measures such as Moran's I or
Getis and Ord G?
Also, S-Plus has a number of interstingly named Cluster Algorithms based on
some previous stand-alone fortran algorithms (agnes, daisy etc.) which
