dataDirectories
A list object, with two elements, one for each of the
two subdirectories included in the main directory. Typically, these will
be separate directories of historical and projection experiments from
climate models. Each element of the list should be named with the name of
the subdirectory and should provide a numeric vector with the starting and
ending years of the data within each of the two subdirectories (e.g.,
list("historical" = c(1990, 1999), "rcp85" = c(2060, 2079))
for a dataFolder with historical experiment data for 1990 to 1999
and RCP8.5 projections for 2060 to 2079).
