Hello,
hopefully someone will remember my previous problem to load the Rcmdr
library from within GNU R resulting in an error message:
libnvidia-tls.so.1: cannot handle TLS data.
Some suggestions have been raised by Christian Schulz and others that
unfortunately didn't work around this error.
Does anyone knows what is the nu-regression option for the type parameter in
svm (from package e1071)? I cannot find any explanation on that and I have a
reasonable understanding on svm fundamentals.
Thanks
Joao Moreira

Hi,
Suppose you have p equations in p unknowns:
F1(x1,x2,...,xp) =0
.
.
.
Fp(x1,x2,...,xp) = 0
You can solve the equivalent minimization problem:
G(x1,x2,...,xp) = F1^2 + ... + Fp^2 = 0
So, you can use optim with G as your objective function.
Hope this is helpful,
Ravi.

do this? Just doing legend(.) doesn't seem to get it.

For sure you have specified wrong x,y values.
See par(usr) for the range or try it interactively using:

Thank you - optim has solved my problem.

I'm using R 1.9.1 on Linux and am having trouble installing a package

I can build the package, but when I try to install it, I get an error like:
Error in FUN(X[[as.integer(1)]], ...) : subscript out
Turns out adding an \alias{} line to the problem Rd file fixed the
issue. I'm somewhat surprised that a missing \alias line leads to error
in FUN(X[[as.interger(1)]], ...) message. Perhaps there was something
else going on (my Rd file is admittedly a bit sloppy)...
