Hi there,

I'd like to do something like this:

   condition = (mySeries.dates.quarter == 1)
   mySeries[condition]

However, this is the error I get:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

    if isnan(x):
TypeError: function not supported for these types, and can't coerce safely

Any idea what's going wrong here?

Thanks for your insight,

Andreas.
