From stats v3.2.5 by R-core R-core@R-project.org

Horizontal Asymptote on the Left Side

Provide an initial guess at the horizontal asymptote on the left side (i.e., small values of x) of the graph of y versus x from the xy object. Primarily used within initial functions for self-starting nonlinear regression models.

Keywords: manip

Usage

NLSstLfAsymptote(xy)

Arguments

xy: a sortedXyData object

Value

A single numeric value estimating the horizontal asymptote for small x.

Examples

library(stats)

DNase.2 <- DNase[ DNase$Run == "2", ]
DN.srt <- sortedXyData( expression(log(conc)), expression(density), DNase.2 )
NLSstLfAsymptote( DN.srt )
