Good Day To You All,
I have installed Ubuntu 9.04 on a Laptop running Vista Business.
When I try to start my little machine,
GRUB keeps telling me there is an error:
Either: Error 25, Error 21, or Error 5.
Once in a while, it is 'Error 22'.
And then there is no way to go any further:

I was using summarize() in a data set in which one of the levels of
the by variable was . The summary statistic was consistently off by
one level and the level was not in the output data frame. I tried
to report it as a bug, but I could not log into the Hmisc bug
reporting website to do so. I
Hello,
I am trying to code Griddy gibbs sampling just with the altorithm which
were considered by Ritter and Tanner(1992) and R to implement Bayesian
GARCH with griddy gibbs.
It is a project for final exam of Bayesian statistics.
If you have source code for Griddy Gibbs,

The deSolve package allows you to specify the model code in C or Fortran.
Thanks to the excellent vignette this works fine. However I have not yet
managed to use forcing functions in C code.
In pure R code this works very well with approxfun() specified outside

Further option would be scatterplot3d in {scatterplot3d} which does
provide facility for sending a vector of axis labels to the x,y, and z

Could there be a way to manipulate the EM algorithms from the mixdist

Possible using RGtk2. Just need to get it into a GdkPixbuf. See
gtkClipboardSetImage(). To get a graphic as a pixbuf, you can use
cairoDevice (drawing to a GdkPixmap and copying over), or output the graphic
to a temporary file and read it back in.

Sorry about the bug, which is now fixed. You can get the fix by entering
source('http://biostat.mc.vanderbilt.edu/cgi-bin/viewvc.cgi/*checkout*/Hmisc/trunk/R/summary.formula.s?rev=661')
until we update the package.

In addition to the example below, Thomas Petzoldt also has two

more easily use his package.

Hi Werner,
AICs of nested models are compared on additive scale, not on multiplicative
scale. So, you have to think about how much the AIC is decreased when you add
the new variable, not the factor by which it is reduced.
If you are doing a stepwise selection based on AIC, then the p-value
Oops. In my previous email I meant to say the following:
In the AIC approach, you include a new variable or delete an existing variable
when the change in the log-likelihood value is 2 or more.

Thank you for your excellent help. I agree method 3 would be the best one,
and this is the one I have been trying to get working (like you described).

I would recommend just running gtkMain(), so that GTK+ blocks R. Then you
need your GUI to call gtkMainQuit() when it's time to kill R.
