clipIt: Create non-linear response by clipping stratigraphic series

In astrochron: A Computational Tool for Astrochronology

Create non-linear response by clipping stratigraphic series

Description

Create non-linear response by clipping stratigraphic series below a threshold value. Alternatively, mute response below a threshold value using a contant divisor. Both approaches will enhance power in modulator (e.g., eccentricity) and diminish power the carrier (e.g., precession).

Usage

clipIt(dat,thresh=NULL,clipval=NULL,clipdiv=NULL,genplot=T,verbose=T)

Arguments

dat	Stratigraphic series. First column should be location (e.g., depth), second column should be data value.
thresh	Clip below what theshold value? By default will clip at mean value.
clipval	What number should be assigned to the clipped values? By default, the value of thresh is used.
clipdiv	Clip using what divisor? A typical value is 2. By default, clipdiv is unity.
genplot	Generate summary plots? (T or F)
verbose	Verbose output? (T or F)
