[R] self-starter functions for y = a + b * c^x

[Christof Kluß]

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 * c^x

Do you know a package that implement such self-starter or is there a
easy way to do it myself?

thx
Christof
