RDCOM Client: processes not terminating
Hello
I am using Duncan Lang's RDCOM Client package (available on
omegahat.org) under R 1.7.0 and Windows XP Pro.
Is this the right forum for questions about this package? In case it is,
here is my question:
Instances of COM objects do not seem to terminate as expected, but leave
residual processes running. For example, if I try the simple example:

Sending emails from R under Windows
Hi
Does anyone know of any R routines to send emails from R, under Windows?
I thought about writing such a facility using the R(D)COM package to
drive e.g. MS Outlook, but I don't want to reinvent the wheel. I have
found a function Sys.mail in the library syskern, but this only works
under Unix by shelling out a mail command.
Thanks,
David

Flipping a heatmap
Hi
I am using the heatmap function in package mva to look at large
correlation matrices visually.
Is there any way to "flip" the output of heatmap plot left-right so
that, if presented with a correlation matrix, it plots the unity
elements in the correlation matrix along a diagonal from top left to
bottom right?
For example:
library(mva)
x = matrix(rnorm(1000), ncol=10)
z = cor(x)

Passing references to data objects into R functions
Hi.
I have the following question about reading from large data objects from
within R functions; I have tried to simplify my problem as much as
possible in what follows.
Imagine I have various large data objects sitting in my global
environment (call them "data1", "data2", ...). I want to write a
function "extract" that extracts some of the rows of a particular

Help with factorized argument in solve.QP
Hi
I'm having problems getting the "factorized" argument in solve.QP (part
of the quadprog library) to work as expected. The helpfile states that
when the factorized argument is set to TRUE, then the function requires
the inverse of a square-root factor of the Hessian instead of the
Hessian itself. That is, when factorized=TRUE, the Dmat argument should
be a matrix R^(-1), such

RODBC: problem saving a new table in an "Excel database"
Hi
I am using package RODBC version 1.0-1 under R version 1.7.1 on Windows
XP Pro. I am having problems writing a new table to an (Excel) database
using sqlSave.
I connect to an empty Excel spreadsheet using odbcConnectExcel (which, I
believe, uses the Microsoft Excel Driver DSN). Then I try and save a new
table to the database(spreadsheet) using SqlSave, but obtain an error

Mapping function dependencies
Hi
Does anyone know of any automatic way of mapping out the dependencies of
a function -- i.e. automatically listing which other functions that
function calls? I tried using all.names or all.vars, but I can't get it
to work on a function: e.g.
> test = function(x, y) return(sin(x + y)*cos(x + y))
> all.names(expression(test))
[1] "test"
I guess the problem is that all.names

pointsize - what is wrong?
Hello!
When I am trying to produce plot with text with pointsize 30 or
greater R sets up a default pointsize of 12 on plot.
I need to set up a large pointsize to make large jpeg or
png files (with good resolution).
I can write text on plot with pointsizes 18,20,22, but i cant
write text with pointsizes 25,26 and greater and i can not
understand - why? Is there are any restrictions in R? Or what?

Cross compiling a package for Windows on Linux
I would like to compile for Windows a rather simple R package that
contains some C code. It does not contain any Fortran code.
I tried the cross-compilation route using the pre-built set of tools
from http://www.devolution.com/~slouken/SDL/Xmingw32/, as described in

Using the sources in r-devel from the rsync site I am able to build
