optim problem, nls regression
...val I want. So I applied
optim(p=pinit,sce, method="L-BFGS-B", lower=c(0,0,0,0,0,0,0), upper=c(10,
10,10,10,10,10,4),control=list(maxit=20000000,temp=20000))
but the program does not run. And I get this message
"Error in optim(p = pinit, sce, method = "L-BFGS-B", lower = pinf, upper =
psup, :
L-BFGS-B needs finite values of fn"
And I don't understand why it doesn't work. Do I forget an option in optim
computation. Or is there an other function instead of optim that I can use.
Thanks in advance

DTMF Issue?
I am using H.323 to create a trunk between Asterisk and Avaya IP Office system. Everything is working correctly, Asterisk
can call Avaya and vise versa. Now I create a conference room with a
user pin in Asterisk. Avaya can call into the conference room, but can
enter the pin number. The error message they are getting is the "invalid pin number". However the pin number
works if they

runif error - maximum limit?
...ng the error below, I think because my n is exceeding the
allowable limit for a vector.
Can anyone confirm, and help with the following questions?
The function and error:
> stPte8 <- rtrunc(rnorm, nx * ny * nsimu, linf=0, mean=as.vector(PTmn),
> sd=as.vector(PTsd))
Error in runif(n, min = pinf, max = psup) : invalid arguments
My total n is calculated by:
nx=4053, ny=4848, nsimu=1000,
n = nx*ny*nsimu = 19,648,994,000
I believe the maximum size of a vector is 2^31-1 (2,147,483,647) - clearly
smaller than my n.
I have done some initial reading about how to deal with large datasets in R,...
