[kepler-users] R-Actor

[Matt Jones]

It looks like your sort column is being treated as a string value, so you
need to convert it to numeric before sorting. Data passed into Kepler's R
actor get represented as text, so this may be why you are seeing it only in
Kepler. Use an R function to convert to numeric and you should be set.
