Compare and plot the yearly values of several objects.

1 2	## S4 method for signature 'G0' compare(...)

...

A list of objects to be compared.

The class of the first element of ... is used to determine the suitable method. The result is plotted with dotplot:

signature(... = "G0"): yearly values of G0d, B0d and D0d.
signature(... = "Gef"): yearly values of Gefd, Befd and Defd.
signature(... = "ProdGCPV"): yearly values of Yf, Gefd and G0d.

###Comparison of different tracker methods
ProdFixed <- prodGCPV(lat = lat, dataRad = prom, keep.night = FALSE)

##The first element rules the method
