Tests for presence of data associated with trees stored as phylo4d objects
Methods that test for the presence of data associated with trees stored as
phylo4d objects.

nData tests for the presence of data associated with the object.
hasTipData and hasNodeData tests for the presence of
data associated with the tips and the internal nodes
respectively. The outcome of the test is based on row names of the
data frame stored in the data slot. If no rows have names
from the set nodeId(x, "tip"), then hasTipData
returns FALSE. Likewise, if no rows have names from the set
nodeId(x, "internal"), then hasNodeData returns
FALSE.
nDatareturns the number of datasets (i.e., columns) associated with the object.
hasTipData, hasNodeData
return TRUE
or FALSE depending whether data associated with the
tree are associated with either tips or internal nodes respectively.
signature(object =
"phylo4d"): whether tree has internal node data
signature(object = "phylo4d"): whether tree has
data associated with its tips
