Hello,
I have a non-linear function (exponential) that I am trying to display
the line with the data in a plot, is there a command similar to abline()
for the function I created, if not what is the best way to display the
fitted line. Example code below.
### Example
z <- c(1,10,15,20,25,30,35,40,45,50,55,60)
p <- c(.02,.08,.2,.45,1.03,2.36,5.37,12.24,27.85,63.39,144.27,328.35)
cnt <- length(z)
fit <- nls(p~(b*exp(m*z)), start=list(m=.1645,b=.017),
control=list(maxiter=200))
plot(p~z)
# want to add fit/line to plot
Thanks,
Doug
