[R] Calculate the latest Z-score of all zoo time series

I have a population of 2000+ zoo time series (but my environment also
contains objects that are not zoo time series). I'm trying to calculate the
latest 90 days Z-Score of all zoo time series, using the following code:
sapply(ls(), LZS )
The LZS function works on individual zoo time series, but not when I try to
use sapply to do it on the whole objects list. I guess this has to do with
the fact that not all objects are zoo. How can I do this correctly?
