If I call
chisq.test(x)$residuals ; I get the *standardized* residuals (even
though it's called residuals)
chisq.test(x)$stdres ; I get the *adjusted* standardized residuals (even
though it's called stdres)
Is this correct?
I think, yes - as documented on the man page.

says
David Meyer (based on C/C++-code by Chih-Chung Chang and Chih-Jen Lin)
is there any chance that you might consider replacing the R code with
the original C/C++?
Thanks a lot!

done
These are warnings and I think that you can safely ignore them.
It looks like the code should replace the line
if (x$datamean)
with something like
if (!is.null(x$datamean))
Yes, I think so too - thanks for reporting this.

Yes, it seems that Prof Meyer hasn't pushed the changes to R forge
yet.
I now did. (There are no other repositories).

'0' and '1' are converted to factors which probably show up as 1
and 2 in the file.
sounds reasonable, thanks.
David, could you please add an option `fac' to `write.matrix.csr',
similar to `read.matrix.csr' which already accepts `fac'?
thanks!

/ sum(L) # this is what is returned
you can instead use
sapply(L, function(lp) {1 / sum(exp(L - lp))})
the above comes from the following equality:
x / (x + y + z) = 1 / (1 + exp(log(y) - log(x)) + exp(log(z) - log(x)))

Dear John,
there *are* indeed 3 classifiers trained, as you can see from
predict(model, iris, decision.values = TRUE)
However, the coefficients are stored in a compressed format -- see

How do I change the size of the text on the legend scale?
This should work with `fontsize', but doesn't which is a bug (fixed in

Also, is there a way to change all the font sizes at once?
Not yet, but this is a good suggestion.
Thanks
