> Hello to all,
> 
> I have two dataframes, the first with two columns sunrise and sunset (for
> 10
> years). Each of these columns is formatted for date time (ex: 01-Jan-2010
> 15:37:00)
> 
> In the second data frame I have GPS information and also a date time
> column
> (same format ).
> 
> What I would like to do is a subset of all the rows from the second
> dataframe that occurred in day time only so between sunrise and sunset.
> There are thousands of lines from multiple GPS so date time might be
> repeated in some rows.
> 
> Any ideas how to accomplish this?
