Compares two filters.
Compares two filters (such as those returned from filter.select). This function returns TRUE is they are the same otherwise returns FALSE.
compare.filters(f1,f2)
f1 |
Filter, such as that returned by |
f2 |
Filter, such as that returned by |
A very simple function. It only needs to check that the family and filter.number components of the filter are the same.
If f1 and f2 are the same the function returns TRUE, otherwise it returns FALSE.
