question about probplot in e1071 package
Dear Thomas,
Reading the probplot?s help page, it looks like it is using qqplot underneath.
Thus, I think this is what you need.
probplot(x, line=FALSE)
#probplot(y, line=FALSE)
qq.y <- qqnorm(y, plot=F)
points(qq.y$y, qq.y$x)
I hope this is useful for you.

2 questions about probplot in package e1071
The contributed package e1071 does exactly what I want except that I
need to have (1) the abscissa and ordinate axes swapped, with the
probability scale on the bottom and the quantiles scale on the LHS.
Using the following example:
library(e1071)
x <- rnorm(100, mean=5)
probplot(x, line=FALSE)
and (2) I need to have lines connecting the plotted symbols, as you get

question about probplot in e1071 package
Hello!
I am using probplot in the e1071 package and want to do something like the
following, only with the the 2nd plot overlaying the first. I can't seem to
make it work. Any suggestions?

**x <- rnorm(100, mean=5)*
*y <- rnorm(100, mean=3)*
*probplot(x, line=FALSE)

Perl array conversion in R to compare plots.
Hello all,
I am using RSPerl package to display plots in R . I want to be able to compare
some data in boxplot and in histogram and in probplot ( from e1071 package)

I have a nested arrray of data ... from perl like the following
data[0][0] = (1,2,3,.....)
data[0][1] = ( 2,1,2,2,2,2,2) - could be different lengths...

I am a freshman of R,but I am interested in it! Those days,I am
learning pages on NIST,with url
http://www.itl.nist.gov/div898/handbook/eda/section3/probplot.htm,
I am meeting a problem about probability plot and I don't know how to
plot a data set with R.
Could somebody tell me the answer,and a example is the best! I will
look forward to your answer.
Thank you very much.

Un-reproductibility of SVM classification with 'e1071' libSVM package
Hello,
When calling several times the svm() function, I get different results.
Do I miss something, or is there some random generation in the C library?
In this second hypothesis, is it possible to fix an eventual seed?
Thank you

x = rnorm(100) # train set
y = rnorm(100)

problem in testing data with e1071 package (SVM Multiclass)

this is the first time I'm using R and e1071 package and SVM multiclass

repeated execution of svm(e1071) gives different results, if probability = TRUE is set
Hello, Connoisseurs!
Please explain to novices, why svm model gives different results in the
loop with the same data? As a result, I can not find the best gamma and
cost parameters. Also tune.svm yields results that can not be repeated.
How can I avoid this?

e1071 SVM, cross-validation and overfitting
I am accustomed to the LIBSVM package, which provides cross-validation
on training with the -v option
% svm-train -v 5 ...
This does 5 fold cross validation while building the model and avoids
over-fitting.
But I don't see how to accomplish that in the e1071 package. (I
learned that svm(... cross=5 ...) only _tests_ using cross-validation
-- it doesn't affect the training.) Can

e1071 - tuning is not giving the best within the range
Hi everybody,
I am new in e1071 and with SVMs. I am trying to understand the performance
of SVMs but I face with a situation that I thought as not meaningful.
I added the R code for you to see what I have done.

Can't load e1071
After upgrading to 1.7.0 under debian linux, I can't get e1071 working
properly.
The first problem I had was that g++-3.0 was the standard compiler but
wasn't installed, so I installed it. e1071 then installed correctly, but I
