S4 objects in the data directory
Hi
[R-2.10.0; suse linux]
I am having difficulty creating S4 objects in the data directory of a
package. I want
to create a bunch of simple S4 objects for use in the examples section
of the Rd files.
It says in R-exts that:
" R code should be ?self-sufficient? and not make use of extra
functionality provided by the package, so that the data file can also be
used without having to load

double gaussian with mixdist: what's wrong?

comparing mixture models (mix function in mixdist package)
Dear List,
We are using the mix() function in the mixdist package to fit mixture models to some of our data.
The package provides a function to compare the fits of nested models using an ANOVA function.
However, we were wondering whether there are methods that can be used to compare models that differ in the number of distributions fitted and/or the shape of the distributions.
Is there a way,

mixdist package in R
Hi, All,
I fitted a 3-component normal mixture model with the mixdist package in R.
How can I get the density of a new data after I fit the model? Is there any
function to do it?
Thanks,
Cindy

Error with Mixdist in R
Dear R User,
I am an electrical engineering student and have just come across a curve fitting problem. I need to find the constituent Gaussian distribution curves fitting the data attached in Workbook1.txt here. I tried to use Mixdist on R but ran into following problem. Can you suggest me where I am going wrong?

Over-constrained? gamma mixtures using R: mix{mixdist}
Dear R-help,
my aim is to fit a constrained 2 component gamma mixture using mix
within package mixdist. The constraints being fixing both of the means
and both of the sigmas. Thus the only unconstrained parameter I wish to
fit is pi the proportions of the mixtures.
This is the code I used:
PP2Pars<-data.frame(c(0.23,0.77), c(9.174,29.54), c(9.983,12.369));

Avoiding choosing parameters with mix[mixdist]
Hi,
I am working on a population of an invasive clam. The data are the size of each clam per station (2mm on average). Each station is found at a different distance from a power nuclear station, so at different water temperatures. The fist step I want to do is to identify cohort size at each station or (zone of water temperature). The second step will be to see whether the size or number of

How to use "mix" to estimate the parameters for mixture gamma distribution?
Dear R users,
Please help me on using "mix" function under package "mixdist".
My data distribution shows there are two components for the mixture distribution: left part is an exponential and right part is a normal. So I plan to use "gamma" mixture distribution to estimate the parameters. Here is what I am using for the "mix" function.

Fitting data to gaussian distributions
Hi!
I need to fit a data that shows up as two gaussians partially
superimposed to the corresponding gaussian distributions, i.e.
data=c(rnorm(100,5,2),rnorm(100,-6,1))
I figured it out how to do it with mle or fitdistr when only one
gaussian is necessary, but not with two or more. Is there a function in
R to do this?
Thank you very much in advance,

installing R on Fedora Core 2 test 2
Just a report for those who want to try this. (Executive
summary: It eventually worked.)
The RPM for Fedora Core 1 did not work because it wanted
libtcl8.3.so and libtk8.3.so, while this distribution had 8.4
instead of 8.3. I didn't try making soft links, thus pretending
that it had 8.3. (I'm planning to install the final version of
Core 2 when it comes out soon. This is a computer I

normal mixture model
Hi, All,
I want to fit a normal mixture model. Which package in R is best for this? I
was using the package 'mixdist', but I need to group the data into groups
before fitting model, and different groupings seem to lead to different
results. What other package can I use which is stable? And are there
packages that can automatically determine the number of components?
Thank you,

Fitting Mixture of Non-Central Student's t Distributions
Dear all,
I am attempting to model some one-dimensional data using a mixture model
of non-central Student's t distributions. However, I haven't been able
to find any R package that provides this functionality.
Could there be a way to "manipulate" the EM algorithms from the mixdist
or mixtools package to fit the model, or do you have any other
suggestions?
If anyone could help

Fitting & evaluating mixture of two Weibull distributions
Hello,
I would like to fit a mixture of two Weibull distributions to my data, estimate the model parameters, and compare the fit of the model to that of a single Weibull distribution.
I have used the mix() function in the 'mixdist' package to fit the mixed distribution, and have got the parameter estimates, however, I have not been able to get the log-likelihood for the fit of this model

Combining Density plots
Hello,
What I am trying to do is:
Generate a density plot of a population of data. This data has a bimodal
distribution so I've isolated a couple of possible sub-populations and I
want to overlay these two density plots over the first to see whether they
are contributing to the bimodal population.
I can do this fine with plot(density(...)) and lines(density(...)) . But

I am trying to use Rcmdr 1.5_4 with R-2.11.1 (order to run to run the new version of misdist-0.5.3 which is built under R-2.11.1). however relimp is required for Rcmdr and the version of relimp_1.0.1 downloaded from CRAN will not work with the latest version of Rcmdr (I get error message telling me to reload it). Is there any way round this problem or will there be a new version relimp that is

the number of components of the mixture model and the stratfied data
Hi,all
with my data,there are more than 1000 quantitative results of antibody
concentrations, there may be 2 components(positive and negative), or 3
components (may be strong positive, positive, and negative), or 4-6
components. Could you tell me how to determine the number of components of
the mixture model? the "anova.mix" in mixdist of the R software seems not
work.

Fitting Mixture of Non-Central Student's t Distributions
Dear Ingmar & Dave,
Thanks a lot for your help and sorry for the late reply.
Finally, I've found a way to separate the mixture of distributions
(empirically). But the gamlss package looks great, I'm sure it will help
me during my further studies.
Kind regards,
Susanne

[PATCH 7/8] drm: Nuke drm_atomic_helper_connector_dpms
It's dead code, the core handles all this directly now.
The only special case is nouveau and tda988x which used one function
for both legacy modeset code and -nv50 atomic world instead of 2
vtables. But amounts to exactly the same.
v2: Rebase over the panel/brideg refactorings in stm/ltdc.
