extracting center of gravity estimates

[EllenY]

Hi Jim,
How would I extract and view the mean and sd of the eastward and northward estimates from the center of gravity plot?
Thank you,
Ellen

function Plot_range_shifts returns a table COG_Table of those estimates. So if you run:

COG = Plot_ranges_shifts( ... )$COG_Table
Area = Plot_ranges_shifts( ... )$EffectiveArea_Table

you'll get COG and effective-area estimates by year with SDs
