Dear users,
is anybody of you aware of a R command to perform laplace transform or
even its inversion?
Thank you very much.

legend - bug with argument angle (PR#1404)
When legend() is used with the angle argument as follows, not only the
boxes beside the legend text, but also the whole legend box is filled
with shading lines.
I think this is not intended:
plot(1:10)
legend(8, 4, c("A", "B"), angle=c(10, 80), fill=NULL, density=20)
I'd suggest as a fix (legend.R of R-1.5.0):

New Package: ipred - Improved predictors
The package ipred is uploaded to CRAN.
The main focus of the package is the calculation of improved predictors
in classification tasks. Misclassification error can be improved by
bootstrap aggregated classification trees and/or
the framework of indirect classification. Furthermore, a unified
interface for the estimation of misclassification error
completes the features of ipred.

Constructing an environment from a data.frame
Code like
df <- data.frame(x=1:10)
y <- 20:29
eval(quote(x+y), env=df)
does what you might expect: it looks for x and y in the data.frame,
and when it doesn't find y there, it looks in the parent environment.
However, sometimes I'd like to construct a single environment out of
df, so that I can pass it to nested functions and get the same
behaviour. Right now, I get the wrong

colnames slow (PR#10470)
Full_Name: Tomas Larsson
Version: 2.6.0
OS: Windows XP
Submission from: (NULL) (198.208.251.24)
This is not a bug, it is a performance issue but I think it should have an easy
fix.
I have a large matrix (about 2,000,000 by 20), when I type colnames(x) it takes
a long time to get the result. However, if I select just the first couple of
rows of the matrix I don't have to wait for the

code problem with the optim() function

I'm estimating an inter-rater coefficient, Aickin (1990)'s alpha. It's been
a long time for me to figure out how to make it work, but it's still of no

NUT: new blazer_usb subdriver proposal
Hello,
I've recently bought two cheap UPS (http://www.ldlc.com/fiche/PB00109242.html).
They're not supported natively by NUT (even though the monitoring
software is UPSilon from megatec).
After some investigation, they almost use the krauler-type
communication already supported in the blazer_usb driver. However, the
UPS won't reply if the language ID is not 0x4095...
