[R] Fitting data from a spectrophotometer.

Dear R-list,

	It is not uncommon for laboratory equipment (e.g. spectrophotometers) to have a linear response in a certain interval and then go into saturation. I wonder if there is an R-function that models this; for instance by estimating the breakpoint and fitting a line below the breakpoint and a constant above.

Best regards
Thomas Poulsen
