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:

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
message.

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

Layout of windows devices
Hi
Is there a way to specify the location on the screen where a new

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)

problems with new checks in R-devel
Below are a few problems I have encountered with the new checks
being done in R-devel.
1/ I have two generics, test.equal and test.equal.tframe. The
first checks that two objects are equal while the second checks
if two objects have equal tframes (time frames). There is no
reason these should have similar arguments but the check seems to
think that test.equal.tframe is a method for test.equal so

Samba logging behavior on new files
Hi list,
I have home made program, which uses File Alteration Monitor library
to watch samba log files for new file creation in samba share
directory.
This technique works fine when I use GNU/Linux machine as client and
it fails when I use Windows machine as client. The cause of failure
is, samba server creates different pattern of logs and sometimes it
does not create log entries on new file

OHLC Plot with EMA in it
Hi there
I have some timeseries data which I plot in a OHLC Plot. In the same
plot I'd like to have the EMA of this timeseries. I tried to add the
EMA point to OHLC with lines(), but this doesn't work. Has anyone an
idea how to handle it?

syskern
The bug list summary reported an error in syskern which I finally
realized is due to a badly chosen example in the help rather an error in
the code. However, I have taken the opportunity to re-evaluate what I
have been trying to do with syskern, since some parts may no longer be
important. Since syskern was intended to address certain problems in
package development I would appreciate other

quantmod's addTA plotting functions
Hi,
I'm having trouble with quantmod's addTA plotting functions. They seem to
work fine when run from the command line. But when run inside a function,
only the last one run is visible. Here's an example.
test.addTA <- function(from = "2010-06-01") {
