How to plot several graphs in a single 2-D figure?
Hi, R-listers
I tried to plot several graphs in a sigle x-y coordinate settings, like the
following:
|(y) s
| ****** s
| ***** s
| sssssssssssssssssss
|_______________________________(x)
where "*" and "s" denote two diffrent plots.
However, when I used
plot(data1); % data1 is the data points of "*"

'nor1mix' for 1-dimensional normal mixture distributions
I have been authoring a very small R package on CRAN, named
"normix" which implements an S3 class "norMix" has plot and
print methods; further, E[X] and Var[X] methods, random number
generation ("r") and density evaluation.
It also provides the 16 "Marron-Wand densities" (known in the (1d)
density estimation business).

univariate normal mixtures
...here a function in R that can estimate the number of normal
distributions k and the means `m_i' for the different normal
distributions from a sample? Or evt. a function that can estimate the
`m_i', when the number of distributions `k' is known?
So far I only found a package, called `normix'. But at first sight it
only provides methods to sample from such distributions and to estimate
the densities; but not to fit such a distribution.
Can someone indicate where I can find an elegant solution?
Thank you in advance

estimating number of clusters ("Null or more")
...subj :-)
My data has too much various distribution families and for every
particular experiment
I need just to decide whether the data is "quite homogeneous" or it has
two or more
clusters. I've revisited the following libraries:
amap, clust, cclust, mclust, multiv, normix, survey.
And I didn't find any ready-to-use general purpose criterion for answering
the question whether the data is "quite homogeneous" or has two or more
clusters. Even for one dimension data.
However, in "cclust" a "clustIndex" might be used as a raw...

rmultinom() -- how \\ via own C code?
I've had a need for multinomial "random number generation"
occasionally. And other people too.
The following code is currently in the
(very small ``not very high importance'') CRAN package normix
--- which I will rename to "nor1mix" very seen because of a
``name registration'' problem
I want to add "this" (well the functionality) to a standard
package -- "mva" probably.
The reason for my post is to ask about importance for C code
(and a an offic...

I've recently written the following {for the R package "normix"}.
The above is really a FAQ.
I think I'd propose to adopt this (or an improvement of it) both
for R and S-plus :
## This is based on rmultz2() from S-news by Alan Zaslavsky & Scott Chasalow
## {and adapted from the R package "combinat"}.
## Arg.names like rbinom();...

Difference in mixture normals and one density
Hello,
I am trying to find out if R can do the following:
I have a mixture of normals say f = 0.2*Normal(2, 5) + 0.8*Normal(3,2)
How do I find the difference in the densities at any particular point of f
and at Normal(2,5)?

Thanks,
Jim.
