Instead of writing something to alter the cumulative math, only adding the labels to the plot instead since a radio button will be implemented?
adding this to the plot output within the block hours function shows correct hours under the "All Seasons" Radio Button
"Breeding Season: ", round(sum(blk.hr[,c(4,5,6,7,8,9)]),digits = 2), "\n",
"Winter Season: ", round(sum(blk.hr[,c(2,3,12,13)]),digits = 2)
