match() returns a vector of the positions of (first) matches of splits in its first argument in its second. %in% is a more intuitive interface as a binary operator, which returns a logical vector indicating whether there is a match or not for each split in its left operand.

# S4 method for Splits,Splits
match(x, table, nomatch = NA_integer_, incomparables = NULL)

in.Splits(x, table)

match(x, table, nomatch = NA_integer_, incomparables = NULL)

# S4 method for Splits,Splits
%in%(x, table)


x, table

Object of class Splits.


Integer value that will be used in place of NA in the case where no match is found.


Ignored. (Included for consistency with generic.)


match() returns an integer vector specifying the position in table that matches each element in x, or nomatch if no match is found.


in.Splits() is an alias for %in%, included for backwards compatibility. It will be deprecated in a future release.

splits1 <- as.Splits(BalancedTree(7))
splits2 <- as.Splits(PectinateTree(7))

match(splits1, splits2)
