If you want to set the sample for a specific year, with dated
daily data, I think you'll have to give the year-start and
year-end dates.  Unless, that is, you add a variable to the data
set that records the year of the observation; then you could
sample on that.

When you load daily data in the first instance, you have the
option of giving dates for all the observations, in which case
gretl will not automatically insert missing values but will accept
your observations as the full data record.

In a loop context it seems that it would be easiest to add a year
variable to the data set.
