Citing R/Packages Question
I used R and the quantreg package in a manuscript that is currently in
the proofs stage. I cited both R and quantreg as suggested by
citation() and noted the version of R and quantreg that I used in the
main text as
"All tests were computed with the R v2.9.0 statistical programming
language (R Development Core 2008). Quantile regressions were conducted
with the quantreg v4.27 package

Repeating values in a list
I have a list that looks like this ...
> have <- list(a=7,b=3,c=1)
> have
$a
[1] 7
$b
[1] 3
$c
[1] 1
and I want to have a simple way to change it to the following without re-typing the values ...
> desire <- list(a=c(7,7),b=c(3,3),c=c(1,1))
> desire
$a
[1] 7 7
$b
[1] 3 3
$c
[1] 1 1
In other words, I need to create the list in desire from the list in have.

plotCI (plotrix) problem
I am attempting to create a plot with intervals "stretched" in the
x-direction using plotCI() in the plotrix package. The same data
provides an appropriate set of intervals when "stretched" in the
y-direction but I only get a lower interval when "stretched" in the
x-direction.
The data are as follows

Function to Define a Function
I am trying to define a general R function that has a function as the output that depends on the user's input arguments (this may make more sense by looking at the toy example below). My real use for this type of code is to allow a user to choose from many parameterizations of the same general model.
My "issue" is that when I compile a package with this type of code in it I get a

Table Modification
I am trying to construct a two-way table where, instead of printing the
two-way frequencies in the table, I would like to print the values of a
third variable that correspond to the frequencies.
For example, the following is easily constructed in R
> fact1 <- factor(sample(LETTERS[1:3],10,replace=TRUE))
> fact2 <- factor(sample(LETTERS[25:26],10,replace=TRUE))

R crash using rpanel on mac os x
Hello,
I've recently discovered a persistent issue with rpanel when running
R.app (2.6.1) on Mac OS X 10.4.11. tcltk and rpanel load without any
apparent error, and the interactive panels appear to work as expected,
however upon closing the panels rpanel has created I get catastrophic
errors and R crashes completely. For the most part R manages to crash
with dignity and work can be saved, but

Error msg in rpanel
I am working on the r panel package. Now if i have a function that uses a
radiogroup button, and if i attempt to run the function from inside the
rpanel menu, i get this error:
Error in panel$intname : $ operator is invalid for atomic vectors
However if i run the function per se i.e. not from inside the rpanel
menu, but by calling it independently, the above error doesn't appear.

kernel density
Hi all (again),
many thanks for the answer to the optimization problem. All is fine now. The
problem now is with kernel estimators in sm. package. I do all the work and
the graphics good, but I need the density function data for each point, and
I don't know how to get it. The only thing I get is the table at the end of

You're welcome! Earlier I tried an experiment with rejection
sampling, which seems to work well for the case where you want
mean of the sampled values to exactly be the mean of the range
being sampled from. The number of tries, even

rpanel rp.tkrplot: x&y when using layout
Hi all,
I wish to use rp.tkrplot from the rpanel package with subplots produced
by layout or split.screen. My problem is that I want to use a click
function, but I can't work out how to convert the x and y values it
produces into the values on the plots as unlike for a single plot they
don't match. For example in the following code the (0,0) and (1,1)
corners of the bottom left plot

The rpanel package
The rpanel package builds on the tcltk package to provide simple
interactive controls for R functions, in particular to provide simple
forms of dynamic graphics. The intention is to make this form of
control particularly easy for R users to implement, with full
documentation. The necessary tcltk variables are managed behind the
scenes so that users need not be concerned with any

help with formula and data= argument
Sorry for posting this twice, but I still have not solved this problem
and am hoping for some assistance.
I am attempting to write a function that is flexible enough to respond
to the user providing a formula (with a data= argument) or not (similar
to plot(x,y) versus plot(y~x,data=data)). I have found a method to work
with this in a simple case but am having trouble determining how to

rpanel / list error
Hi All,
I have created a simulation that works perfect and I have the results been
returned in a list as I have multiple values. I then decided to include some
user interaction by using the package rpanel, I now get the error:
object of type 'builtin' is not subsettable
when I attempted to have the return my list with the results .
Any help needed. I can also upload code if needs be.

Integration of mixed normal distribution
Hi,
I already found a conversation on the integration of a normal
distribution and two
suggested solutions
(https://stat.ethz.ch/pipermail/r-help/2007-January/124008.html):
1) integrate(dnorm, 0,1, mean = 0, sd = 1.2)
and
2) pnorm(1, mean = 0, sd = 1.2) - pnorm(0, mean = 0, sd = 1.2)
where the pnorm-approach is supposed to be faster and with higher precision.

Interactive plots with R
Hi,
I wrote some simple rpanel package script for visual spectral data comparison.
At this example i have a three samples and i want to zoom through x and y
axis to compare differences between samples. With my script below I can zoom
to some data region and add some other spetra to the plot, through text input
field.
But I can't figure out, how to change axis scaling for all displayed

Best Way to Compute/Approximate(?) Probabilty of a Point in a Given Distribution
AFAIK, R only has "pnorm" which computes the probability of getting a
value smaller or equal to "x" from
a normal distribution N[mean,stdev]. For example:
R> pnorm(0, 4, 10)
[1] 0.3446
means there is 34.46% chance of getting a value equal to or smaller
than 0 from a N(4, 10) distribution.
What I intend to get is: given the observed value "x", mean, and stdev
