unionPositions
Positions Object Union With Tolerance
Description
Makes a union of numeric or calendar positions (that is, positions of 
series objects (which can be numeric), time vectors, or sequences)  
objects using localzone and matchtol as in the seriesMerge and align 
functions. 
Usage
unionPositions(..., localzone = FALSE, matchtol = 0)
Arguments
| ... | the positions objects to be joined. | 
| localzone | a logical value. If TRUE, creates a union by matching with all 
passed-in positions in their local time zones, instead of with 
the absolute GMT times. (The positions must be calendar-based.) | 
| matchtol | the tolerance for matching positions. Positions that match within matchtol are 
not duplicated in the output. | 
 
Value
|  | returns a new positions object containing all of the input positions, with  
duplicates (as defined by matchtol and localzone) removed. | 
   
|  | returns numeric(0) if no ... arguments are given. |
