I recommend posting this on a mathematics discussion forum like Stack Exchange
and (re-)reading the Posting Guide for this mailing list.
I think you are going to need to re-write your model function to algebraically
combine your original model along with the constraint, and then use the

Yes , it does. Perhaps you'd be kind enough to provide a sample of
your data --dput(sample(pauls.data)) on gist.github.com -- and what

On Wed,
Depending on exactly what you mean by"unsupervised", many.
See here under "Decomposition and filtering":
https://cran.r-project.org/web/views/TimeSeries.html
You could also search on something like "smooth time series R" etc.
However, assuming I have correcty interpreted "unsupervised
Dear friends,
Hope you are all doing great. I would like to know if R has any
unsupervised algorithm to generate forecasts for historical data.
Any help will be greatly appreciated,
Best regards,

Dear All,
I have a problem I haver been struggling with for a while: I need to
carry out a non-linear fit (and this is the
easy part).
I have a set of discrete values {x1,x2...xN} and the corresponding
{y1, y2...yN}. The difficulty is that I would like the linear fit to
preserve the sum of the
Hola Jaume:
Lo más rápido para ver el código, al ser un método S4 es escribir:
findMethods(biovars)
La descripción de la función (con las definiciones y comentarios si los
tuviese) los tendrías que ver rebuscando en el código fuente del
paquete. Generalmente en la carpeta "R" del paquete
If you specifically want to know which packages were loaded by the script
then using a vanilla version of R (i.e. one where only base packages are
loaded):
vanilla_search <- search()
source("myRprg.R")
setdiff(search(), vanilla_search)

Sorry to say so, but you seem confused.
The "sigma" in physics parlance is presumably the s.e. of the estimate so the
"number of sigmas" equal the t statistic, in this case 5.738. However, use of
that measure ignores the t distribution, effectively assuming that there are
infinite df (and 24

Again, this only works (I think) for the simple sort of case of your

You need to recursively walk the parse tree/AST. See, e.g.,

Hi,
I have read an R program with
expr <- parse("myRprg.R")
How can I extract the parameters of a specifc R command, e.g. "library"?
So, if myprg.R containes the lines
library("xyz")
library("abc")
then I would like to get "xyz" and "abc" back from expr.
Thanks in advance
Sigbert
