Hi all,
I am a senior student of MIS department at Bogazici University, Istanbul.
My graduation project's focus is on data mining using R.
I would like to write a function which takes find best(or near to best) cut
points to discretize continuous values to minimize the conditional entropy
based
Dear List,
After updating to R 3.10 and Bioconductor 2.14, I'm having a rather frustrating
error whenever I try using function like cairo_ps to save eps figures as
demonstrated in the following example:

plot(c(1:10),c(1:10))
Fontconfig error: Cannot load default config
Hi R experts,
My original graph was plotted, and for some reason, I need to add
extra '2' inches on the left side.
Meanwhile, I want to keep everything unchanged. Particularly, the
length-width ratio for each panel of the original graph is nice,
therefore I want to keep the original ratio

May be this helps:

Dear Michael,
You can use geom_smooth directly.
ggplot(pred, aes(x = Age, y = Better)) + geom_smooth(method = glm, family =

Hi,
I'm trying to use SSlogis to fit a logistic model, but I get the error:
step factor 0.000488281 reduced below 'minFactor' of 0.000976562
I know I can use the nls.control within nls to help with this error, but the
nls call that is producing this error looks to be from _within_ SSlogis. So
does anyone have a kaveri based system with R recompiled to use its GPU?
is this even possible today?

filled.contour() is written in R as a layout wrapper for .filled.contour(),
which does the actual plotting. The code handles the construction of the key
legend. I have added a parameter
key.extend = FALSE to the function and I believe it does what you were asking

Dear,
I am writing you following a rather old post I found
herehttps://stat.ethz.ch/pipermail/r-help/2006-May/105142.html where Ronggui

Currently, I am in the process of doing panel data regressions in R and I am

I think there is far too little information here to be able to even start
guessing. But if you provide a small, reproducible example of the problem, I am
sure you will get an answer in very short time. Let me recommend that you read
the posting guide ...

Hi AK,
Thanks very much for the updated code.
My simulated results are even more consistent with observations after apply the
updated version of the code.
