I am installing "nnet" package into Splus5 and have several problems.
Please let me know if you are familiar with them.
I am using Version 5.0 Release 3 for Linux 2.0.32 : 1998.
The source code of nnet package is from http://lib.stat.cmu.edu/S/nnet
which is written for Splus3.1. I don't know whether this make much
difference
1.The first problem: while trying the example code, I got an error
message. What is the reason?
> ir <- rbind(iris[,,1],iris[,,2],iris[,,3])
> ir1 <- nnet(ir[samp,], targets[samp,],size=2, rang=0.1, decay=5e-4,
maxit=200)
> smple <- c(sample(1:50,25), sample(51:100,25), sample(101:150,25))
Problem: Object "targets" not found
Use traceback() to see the call stack
2. The command (taken from the file "INSTALL")
Splus5 COMPILE nnet.c
is not recognized.
3. Finally, I wonder whether there is a nnet package for R. I didn't find
it in http://lib.stat.cmu.edu/R/CRAN/src/contrib/PACKAGES.html,
even though on R's FAQ nnet library has been listed.
