fitCusp: Cusp Line Shape Fit
In bgrich/JLstartup: Start-up Functions for Analysis

Description Usage Arguments Details

Performs a fit to the cusp line shape dcusp

fitCusp(x, y, height, width, xoff, yoff)

fitCusp2(x, y, height, width, xoff, yoff)

fitCusp3(x, y, height, width, xoff)

`x`	a numeric vector. The x coordinates to be fit.
`y`	a numeric vector. The y coordinates to be fit.
`height`	a numeric. An initial guess to the height of the distribution.
`width`	a numeric. An initial guess to the width of the distribution.
`xoff`	a numeric. An initial guess to the x-offset of the distribution.
`yoff`	a numeric. An initial guess to the y-offset of the distribution.

These functions perform fits of provided data to the cusp line shape dcusp using optim. The base version of fitCusp using a max iteration number of 300 in optim. fitCusp2 uses a max iteration number of 1000. fitCusp3 also uses a max iteration number of 1000, but removes the y-offset.
