Passing function arguments
...ve made a replica, less complicated function to show my problem, and how
i've made a work around for this. However i suspect there is a _FAR_ better
way of doing this.
If i do:
BuildDecayModel <- function(x = "this", y = "that", data = model.data) {
model <- nls(y ~ SSexp(x, y0, b), data = model.data)
return(model)
}
...
"Error in lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...) :
0 (non-NA) cases"
This function returns an error because the args are passed as "this" and
"that" to the model, and so fails (correct?)
If...

self-starter functions for y = a + b * c^x
Hi
there are some predefined self-start functions, like SSmicmen, SSbiexp,
SSasymp, SSasympOff, SSasympOrig, SSgompertz, SSflp, SSlogis, SSweibull,
Quadratic, Qubic, SSexp (nlrwr)
Btw, do you know graphic examples for this functions?
The SSexpDecay (exponential decay) for y = (y0 - plateau)*exp(-k*x) +
plateau from
http://stats.stackexchange.com/questions/17126/how-can-i-make-my-r-nls-model-more-stable
works fine, too.
But now I search a self-starter for y = a + b...

Running microsoft vss under wine
Hello,
I am using wine on RH9.
I am running Visual Source Safe like thus wine --ssexp.exe
THe VSS GUI starts OK.
the Visual Source Safe database is on Windows Partition.
This Windows Partition is mounted on my Linux like thus:
