I've run into this before and didn't find a convenient way in Compute to do
this consistently.  Because some functions don't like NaNs or NaNQs, I've
usually had to do some filtering prior to Import or eliminating the cause
of the NaNs in the files.

If there is a way to do it in Compute, I would find it useful.

Subject:    [opendx-users] De-NaNifying data



     I imported some fields that have sporatic NaNs and wanted to exclude
those values with Include.  Is there a Compute function or something I
should be using to do this?

     I know NaNs compare strangely, which helps explain why
Include( -10000 <= x <= 10000 ) didn't work, but
Include( x <= -10000, exclude ) did.
