clipIt {astrochron}

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)
