R Documentation

A Function to Attempt a Crude Fit of Data to a Hyperbola

Description

This function is not intended for direct use. It attempts to generate an approximate fit of a data set to a hyperbola, returning a parameter set for use in intializing the main function conicFit .

Usage

bootHyperbola(x, y = NULL, maxiter = 10000, ...)

Arguments

`x`	vector of x-values, or a Nx2 array of x and y values. In the latter case, the input `y` is ignored.
`y`	vector of y-values.
`maxiter`	A 'safety' limiter on the number of iterations to try before giving up.
`...`	possible other arguments to be passed to future upgrades

Value

`parA`	the new 6-parameter set defining the non-rotated conic.
`parAr`	the new 6-parameter set defining the rotated conic.
`theta`	the angle of rotation between ParA and ParAr
`fitdat`	the information returned from `optim`
