precession: Compute June 1, 65 N precession index

In jrevenaugh/TSAUMN: Time Series Analysis Tools Used in ESCI5201 at the University of Minnesota

Description

Compute June 1, 65 N precession index with one of three orbital calculations.

Usage

precession(time = seq(-2e+06, 0, 1000), model = "la04")

Arguments

time	vector of years at which to calculate precession. Negative for past times.
model	one of la04, ber78 or ber90 to select orbital calculation, defaults to la04 (Laskar 2004)

Examples

p <- precession( time = seq( -8e5, 0, 1e3 ), model = "ber78" )
