[R] fit an exponential curve

Dear useRs, I have the following plot: pos - c(27/44, 11/32, 8/40, 4/42, 3/40, 4/40, 2/40) tmin - c(15.8, 12.6, 10.5, 2.4, 5.2, 8.5, 7.9) plot(tmin, pos) I would like to fit an exponential curve to it. How could I be able to do this? Thanks in advance, Rafael.

Hi Rafael, Here is a suggestion: # Data pos - c(27/44, 11/32, 8/40, 4/42, 3/40, 4/40, 2/40) tmin - c(15.8, 12.6, 10.5, 2.4, 5.2, 8.5, 7.9) d - data.frame(pos, tmin) # Non-linear model fit - nls(pos ~ a*tmin^b, data = d, start = list(a = .1, b = .1),
