    Usage
    brts2phylo(times, root = FALSE, tip.label = NULL)
 
    
    Arguments
- times
- Set of branching times 
- root
- When root is FALSE, the largest branching time will be assumed to be
the crown age. When root is TRUE, it will be the stem age. 
- tip.label
- Tip labels. If set to NULL, the labels will be t1, t2, etc. 
 
    
    Value
-  phy
