Re: [R] S curve via R

2006-07-26 Thread Johannes Hüsing
 Hello sir:
 How can I get S curve function via R?
 For SPSS,the function is:y=exp(b0+b1/x)


I am not sure if this is the answer you want, but

Scurve - function(x, b0=0, b1=1) {
exp(b0+b1/x)
}

should do what you request.

Greetings


Johannes
