x |
A tframe or tframed object. |
... |
Additional tframe or tframed objects. |
These functions calculate the start and end of each object in the argument and return a result by comparing across objects. Thus, latestStart returns the start date of the object which starts latest and latestStartIndex returns the corresponding index of the object in the argument list.
A date or index.
