Dear List,
This is my first post, and I'm a relatively new R user trying to work out a
mixed effects model using lme() with random effects, and a correlation
structure, and have looked over the archives, & R help on lme, corClasses, &
etc extensively for clues. My programming experience is minimal
Dear List,
I was trying to verify that I could use extend.series in the wavelets
package and kept getting an error when trying to use method="zero". I'm not
seeing where my syntax has gone awry.
According to the documentation, [see ?extend.series]
" method: A character string indicating which ex
Hi people,
I want to obtain the adjusted r-square given a set of coefficients (without
the intercept), and I don't know if there is a function that does it.

Dear Alexandra,
Without knowing what routine you were using that returned an R-Square value

Dear list,
I had some confusion regarding what function too use in order too relate
results from spec.pgram() too a chi-square distribution. The documentation
indicates that the PSD estimate can be approximated by a chi-square
distribution with 2 degrees of freedom, but I am having trouble figu
Dear list,
What on earth is spec.pgram() normalized too? If you would like to skip my
proof as to why it's not normed too the mean squared or sum squared
amplitude of the discrete function a[], feel free too skip the rest of the
message. If it is, but you know why it's not exact in spec.pgram() wh
wer your question about the reference distribution.
The help page does not say it is `normalized' at all: it says it computes
the peridogram, and you seem unaware of the definitions of the latter (and
beware, there are more than one).

Dear Tom,
Short answer, if your using spec.pgram(), use the smoothing kernel to get a
better estimate at the frequency centered in the bandwidth. If your
frequency bin of interest is wider than the bandwidth of the kernel, average
across frequencies (I think). The estimate appears to be normalized
Dear List-mates,
Is there a corStruct constructor already written to calculate the shape of
the spectral density for linear models using Fourier estimates (e.g. terms
for a linear model derived from the frequency domain)? I have data with a
long memory process but do not want to destroy it by taki
Dear List-mates,
I have been trying to set up a 4x8 trellis plot (that is, 4 columns, 8
rows), and would like to have the axis limits set based on the data range of
rows (for ylim) and columns (for xlim). I've been using the call:

Dear Templ (& Others),
Thank you for pointing out the contributed papers. It is one of those things
that I have been introduced to more than once, but I personally never
remembered to check the section out while in the acute phase of
"problem-can't do it-what the heck is going on."
Dear Michael,
Dear list mates,
Are {utils} dialog box functions, and winMenuAdd... functions used to change
(e.g. Console) menus, platform dependent?
I'm writing a script loaded with .First that provides first time users in a
lab course with the ability to select, load, and change between what I
called a 'ses
ines?
Respecftully,
KeithC.

Dear List-mates,
I'm trying to read a tk window menu from a file using {svWidgets} and
'menus.txt' but am receiving Warnings without seeing the desired
consequences of the call.

Do I need to install PCRE-6.6 for this to start working?

that it is a Tk menu. So, rewrite your menu definition file as:
>
> $Tk.KSesnMain
> |$MenuTest

Note also that KSesnMain must point to a valid Tk window previously
constructed.

Dear List-mates,
I just read Mathias, et al (2004) about their {nuSpectral} package in R for
a weighted leased squares method for unevenly sampled time-series.
What kind of experiences have users had with the package?
R-Site Search came up blank. I've never asked about a package that was

Dear list,
How is the tolerance for a model parameter in an lm() call extracted?
I did not see a solution in the documentation for lm(), or predict(), nor in the
archives using 'tolerance' as the search string. I also checked into the nlme
package, though nothing popped out at me.
Sincerely,
Kei
