From stats v3.2.2 by R-core R-core@R-project.org

Horizontal Asymptote on the Right Side

Provide an initial guess at the horizontal asymptote on the right side (i.e., large 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

NLSstRtAsymptote(xy)

Arguments

xy: a sortedXyData object

Value

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

Examples

library(stats)

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