cog(-Inf) hangs browser

[IanWorthington]

A cog() that contains a -Inf (from, say, a max() of a data column that contains just NAs), will cause the browser to hang when attempting to FILTER on that cog. Changing it to NA seems to work fine.

If you don't mind trying this on a new version of Trelliscope, see here: https://trelliscope.org/trelliscope/articles/trelliscope.html. Note that the R interface has changed quite a bit, hopefully for the better, so there will be some learning curve, but the principles are the same.
