This function scans a list of trees, and returns a list with the
duplicate trees removed. By default the labelled topologies are
compared.

unique(x, incomparables = FALSE,
use.edge.length = FALSE,
use.tip.label = TRUE, ...)
Arguments

unused (for compatibility with the generic).
use.edge.length
a logical specifying whether to consider the edge
