Max/Min w/ Non-linear constraints
Hi all,
How do people do non-linear constrained maximization in R? If in C, are
there any packages people would recommend as being particularly easy to
interface/hack to work with R? And if not, does anyone want me to?

Generalized Error Distribution (Exponential Power) CDF?

Just a random shot in the dark. Does anyone have/know of a function for the
CDF of a generalized error dist?

Apply command on vectors
Hi all,
I keep running into a small problem in my programming, and I'm sure there's
an elegant way around it...
I often want to use apply() on a matrix with a variable number of columns. It
works just fine unless the number of columns is one, in which case the matrix
becomes a vector, and apply() complains. Example below:
-----------------------------
a.matrix <- matrix(rnorm(6),

Animating a persp plot: non-constant scaling?
Hi all,
I'm making an animation of a rotating persp plot of some data. It's easy,
really: I just plot the persp in a loop over the theta parameter, saving
each plot, and then chain them together with ImageMagick (as suggested on
Paul Johnson's R-tips page).
But... when you run the animation, because each graph is individually
re-scaled, the image is not the same size in each

"Invalid character 32" problem with Pager??
Hi all,
I'm having a very minor problem. Most every time I use the pager (I think) I
get the following error about character 32. It works fine, but the error is
a bit annoying.

state-space models and kalman filter
Hello again,
A different but related question to my last one:
Does anyone know if one can easily estimate state-space models
using ML and the kalman filter using R? I would be especially
interested in a relatively flexible function that would allow for
estimation
of hyperparameters, or could be made to do so.
Thanks

Error Installing Package with Dependency on "Matrix"
I'm attempting to update to R 2.15.1, and I'm having trouble with a package
that depends on the "Matrix" package. I've created a dummy package
consisting only of a DESCRIPTION file that specifies the dependence on
"Matrix", a NAMESPACE file, and an R directory, containing a single
function, "square <- function(x) { return (x*x) }". When I try to

Repeated Aggregation with data.table
I have been using ddply to do aggregation, and I frequently define a
single aggregation function that I use to aggregate over different
groups. For example,
require(plyr)
dat <- data.frame(x = sample(3, 100, replace=TRUE), y = sample(3, 100,
replace = TRUE), z = rnorm(100))
f <- function(x) { data.frame(mean.z = mean(x$z), sd.z = sd(x$z)) }

Thinning Lattice Plot
Is there an easy way to "thin" a lattice plot? I often create plots from
large data sets, and use the "pdf" command to save them to a file, but the
resulting files can be huge, because every point in the underlying dataset
is rendered in the plot, even though it isn't possible to see that much
detail.
For example:
require(Hmisc)
x <- rnorm(1e6)

Multiple Line Plots with xyplot
I'm trying to make multiple line plots, each with a different color, using the xyplot command. Specifically, I have an NxK matrix Y and an Nx1 matrix x. I would like the plot to contain a line for each (x, Y[,i]), i=1:K. I know something like
xyplot(Y[,1] + Y[,2] + Y[,3] ~ x, type='l')
will work, but if Y is large, this notation can get very awkward. Is there a way to do something

Scaling Lattice Graphics for tikzDevice
I'm trying to use lattice graphics to produce some small plots for inclusion in a LaTeX file. I want the LaTeX fonts to be used in the plots, but to be scaled down to match the size of the plot. I have written the following code to apply a scaling factor to all the "cex" and "padding" entries in the trellis parameters, but there is still a large white space between the key

Re: [slugnet] Password Expiry
Hi Elliot,
I couldn't find anything related to smbpasswd expiry.
Since u have "unix password sync = true", just a wild guess, if u could
turn off password ageing in unix passwd file (man passwd for more detail)
and see if problem persists.

\VignetteKeywords{}, for KEYWORDS or for free-tagging?
Hi R-devel,
[Question]:
* Is there a KEYWORDS file to lookup 'keywords' to supply
the vignette command, '\VignetteKeywords{}'?
-or, is the pkg writer free to tag the vignette using any
keywords he/she chooses? i.e., free-tagging.
Thank you,

Cumsum in Lattice Panel Function
I'm trying to create an xyplot with a "groups" argument where the y-variable
is the cumsum of the values stored in the input data frame. I almost have
it, but I can't get it to automatically adjust the y-axis scale. How do I
get the y-axis to automatically scale as it would have if the cumsum values
had been stored in the data frame?
Here is the code I have so far:

Pressing number 2 in dialplan
Hello!
I am having an odd problem in that when the caller dials extension "2"
in a dialplan, the system waits 3 to 4 seconds before proceeding.
This doesn't happen when any other other extensions are dialed,
including an identical dialplan on other another extension!
Is this a bug?
Later,
Elliot
