lm length
Hi all,
I wanto to run a plot about the levels of a variable parting on an ols
regression. The regression in done on the rate of return of the variable.
Imagine R_{t}=a+b*R_{t-1}
So If P, the "estimated" price would be P_{t}=P_{t-1}*R_{t}
Imagine that I obtain lm fitted values and the original
R_{t}, R_{t-1} are [1000,1] dimmension...
How it is posible to obtain also 1000,1 fitted

computing functions with Euler's number (e^n)
I am trying to create a set of wavelets in frequency space--namely Cauchy
wavelets for an intensity analysis (von Tscharner, 2000). The wavelets are
defined by the following formula:
[(f/cf)^(cf*scale)]*[e^((-f/cf)+1)^(cf*scale)]
where *f *is frequency of length *n*, *cf* is center frequency (defined
below) and is an array of *j *columns and *n* row, and scale is a constant.
cf = (1/scale)*(j

Long equation in documentation
I have a long equation that I need to break in the R documentation of a package or it trails off the right hand side of the page. Here's the formula:
\deqn{Cov(r_{ist}, r_{iuv})= [.5\rho_{ist}\rho_{iuv}(\rho_{isu}^2 + \rho_{isv}^2 + \rho_{itu}^2 + \rho_{itv}^2) + \rho_{isu}\rho_{itv}+ \rho_{isv}\rho_{itu}-(\rho_{ist}\rho_{isu}\rho_{isv} + \rho_{its}\rho_{itu}\rho_{itv}) +

prefix 'R_' when calling external code
I noticed that in
https://svn.r-project.org/R/trunk/src/library/stats/R/loess.R
that we are now calling R_loess_raw, R_lowesw, R_lowesp, etc. I'm
interested to know what is the benefit/reason for the 'R_', as I am
unfamiliar with this prefix and do not see it mentioned in 'Writing R
Extensions.'
Thanks,

[LLVMdev] Reviving the new LLVM concurrency model
The current memory model section ends with the following discussions:
"Note that in cases where none of the atomic intrinsics are used, this
model places only one restriction on IR transformations on top of what
is required for single-threaded execution: introducing a store to a
byte which might not otherwise be stored to can introduce undefined

dnbinom(,size<1,)=0 (PR#842)
This came up on r-help but indicates a bug.
dnbinom(x,n,p) calls dbinom_raw(n-1,...)
which returns 0 for n<1.

help: ks test fit Poisson-ness (D and p) with one sample data
for a silly question, wondering how to test fit with the one sample as follow.
I have read _fitting distributions with R_, but that doesn't answer my specific question.
inclined to use Kolmogorov-Smirnov D, and its associative p value.
much appreciation!

a question about linear mixed model in R
Dear all,
I have a somewhat unusual linear mixed model that I can't seem
to code in lme. It's only unusual in that one random effect is
applied only to some of the observations (I have an indicator
variable
that specifies which observations have this random effect).
The model is:
X_hijk = alpha_h + h * b_i + r_(ij) + e_hijk , where
h = 0 or 1 (indicator)
i = 1, ..., N
j = 1,

Symlink to directories seem recursively for Microsoft Workgroup Add-On for MS-DOS clients

error:Ran out of lanemask bits to represent subregister
Do your 32768 registers also have sub registers?
I can't tell you exactly what to change. I'm not familiar with the code. I
would just be running grep or something.

I don't understand this
For reasons which I'll spare you, I'm writing a program to analyse
R source code. This has led me to probe some of the darker corners
of R syntax to find out what is supposed to happen.
Now, from reading the R documentation (and the New S book &c) I know
perfectly well that
f(a, b, etc) <- x
is supposed to turn into
a <- "f<-"(a, b, etc, value=x)

Efficient sampling from a discrete distribution in R
Hello r-help,
As far as I've seen, there is no function in R dedicated to sampling
from a discrete distribution with a specified mass function. The
standard library doesn't come with anything called rdiscrete or rpmf,
and I can't find any such thing on the cheat sheet or in the
Probability Distributions chapter of _An Introduction to R_. Googling
also didn't bring back anything.
