Hello,
I am trying to figure out if there is a way to order the left side of a Sankey
diagram from most frequent to least frequent. I am using R version 3.2.1 and
using googleVis version 0.5.9 for the Sankey. I've tried sorting, but that does
not work. Is there anyway to force it to arrange the left ("before") side in
decreasing frequency? Something I am missing? Does not have to be using
googleVis. Thank you!

Example of the data I have, in a csv file:
before after
A B
A B
A B
A C
A A
A A
A B
D E
F B
F B
F F
G H
G A
I reformat the data in R so it looks like this:
before after count
A B 4
A C 1
A A 2
D E 1
F B 2
F F 1
G H 1
G A 1
Then plot using this:
plot( gvisSankey (data, from="before", to="after", weight="freq",
options=list(width=600, height=800,
sankey="{iterations: 2}")))
