load it by typing library(car). The actual code for levene's test is

Hello togheter,
I've installed R with this instruction:
http://edtechdev.blogspot.com/2009/03/r-in-ubuntu-intrepid.html
After that I tried to install odfWeave with this:
install.packages(odfWeave)
Then there came this warning:
Warnung in install.packages(odfWeave) :
Argument 'lib' missing:
I've already found the solution myself:
the package odfWeave depends on package XML
to configure the package XML the libxml2-devel package in ubuntu is
needed.
You get that with typing in the console:
sudo apt-get install libxml2-devel

Hi Gundala,
One easy way is to roll your own axes:

Hi Gundala,
If you want your plotting axes to appear in colour,
try

Hi,
If you have a look at the help for par (type ?par at the prompt) and
then have a read of the section on 'cex' that should point you in the

You can use the caret or ipred packages. caret has it setup for

If you try
library(MASS)
example(lda)
predict(z)$posterior
You will see there are very many posterior probabilities there, too, which
differe from 1 by round-off error at most. So your data are not unique.
I don't get why you don't get it.
