Using the dataset "dat" (found below), I'm seeking a way to condense down
the data.frame such that each "site" (i.e., "CID_1"..."CID_13") has a
maximum of 7 rows of post-processed data, where the first 6 have the
highest "countPercentage" and the 7th row is the sum of "countPercentage"
from all other rows within that "site", and it is assigned the name
"Other". So, for the first two sites in the provided data.frame, CID_1 &
CID_10, they would reduce to:
CID_1 Cyanobacteria 37.48
CID_1 Proteobacteria 29.24
CID_1 Bacteroidetes 15.83
CID_1 Verrucomicrobia 6.38
CID_1 Firmicutes 2.30
CID_1 Acidobacteria 2.08
CID_1 Other 6.68
CID_10 Proteobacteria 35.37
CID_10 Bacteroidetes 25.19
CID_10 Cyanobacteria 23.29
CID_10 Verrucomicrobia 6.97
CID_10 Acidobacteria 1.99
CID_10 Actinobacteria 1.64
CID_10 Other 5.55
