Dear list,I am quite new to the world of biostatistics and I encounter some
issues in the precise understanding of the coxph function of the survival
package.I have a set of survival data (patient who had (or died from) a
breast cancer) I'd like to see which are the variables that might cause dead
Hi everyone,
I'm asked to perform a heteroskedasticity test for a model,
Usually, I use lmtest:bptest and it works fine,
But this model I have to test was estimated using nlme:lme, and the bptest
function seems to complain about it (no R-Squared I guess?),
So I wonder: Does it exist a bptest for
clare each functions in the NAMESPACE file. Since I have a lot
of functions, it's not very easy.
Is there a way to exports all methods in one statement ? or is there a
tool which can help generating the NAMESPACE file ?
Thanks for your help,
Sylvain.
PS: Could you please CC me in your repli
amples use existing .dbf files.
I just have a (serie of) text file(s) looking like this:
For example, for the French Region Burgundy:
any idea welcome,
sylvain
(If anayone is interested with that type of data, they're available at
the INSEE website
along with loads of information on the
distance or area calculus (which
do not need to be extremely precise...)

Hello R users,
When I type
d <- density(MyData$x)
I obtain a density object I can plot,
But I wonder if there is a way to easily compute the length of the
density curve ?
( I imagine I could compute the distances between the 512 equally
spaced points using their x and y, but does it exist a sm
Yes, sure (and I just did it again)

that store, he probably also goes to this one...")
So, I have a simple question: which method you would choose for computing
and plotting the links between a set of dummy variable?

Notice the database files are copied in a temporary directory, thus any
update made to the database is not written in the .odb file untill the
odb.close call, so simultaneous access to a same database (via R and
OpenOffice) should not be considered.
Any suggestion or comment may

PS: for the moment I used a trick with the fg argument passed to par which
allows to pass a colour for the border of the polygons.
