Hello I'm a newbie to the list. I recently installed R on a Redhat 9.0
system, when I come to plot anything it does not bring up a graphics

that doesn't bring up a window either. I would greatly appreciate any
Hello,
When I plot or look at the error rate vector for a random forest
(rf$err.rate) it looks like a descending function except for a few first
points of the vector with error rates values lower(sometimes much lower)
than the general level of error rates for a forest with such number of trees

It is the best book and has a large section devoted to using the nnet

Of course, you need to understand the theory first;-D

Please tell us the version of the package, the version of R, and the

Sounds like you should upgrade to a newer version of the randomForest
package. In Breiman's original code, he is counting the number of
misclassified cases and dividing that by the total number of

Andy,
Does it mean that the error rate does increase as long as the aggregating
number of out-of-bag cases reaches the number of all cases? or, in other
words, because the number of points being predicted (right or wrong) gets
larger at the first steps of the process?
If it so then it's all

I thought glm was a minimize the deviations approach, which is different
from maximize likelihood.
No, it's maximum

It looks like you have compiled R without support for X11, so the

Vladimir,
The OOB error rate estimates for the first few iterations is necessarily
variable, as the number of cases that have been OOB (and therefore
predicted) is relatively small. As an example:
library(randomForest)
data(iris)
err1 - err2 - numeric(10)
set.seed(1)
for(i in 1:10) err1[i]
Why in the codigo that continues when is erased the menubutton herself is
not erased tambien the variable one opc, though itself deberia you erase
with the assign?
library(tcltk)
vectPath-c()
opc-tclVar(init= )

Well, there's as.vector(rbind(x,z)) at least... I don't
as.vector(rbind(x,z))or c(rbind(x,y))
