vbtinq: Using vector to visit vector binary tree
In VBTree: Vector Binary Tree to Make Your Data Management More Efficient

Description Usage Arguments Value See Also Examples

Visit the vector binary tree and return a double list through specific assigment determined by the argument inq.

1	vbtinq(x, inq)

`x`	The vector binary tree to be visited. Traversal is available by setting -1 in desired layer.
`inq`	An integer vector to determine desired location. The length of `inq` should be the same as the layers of visited vector binary tree. If any assignment in specificed layer exceeds its intrinsic length of visited vector binary tree layer, all elements will be returned in this layer.

Return a double list according to the argument inq.

#Make vector binary tree:
colnamevbt <- dl2vbt(chrvec2dl(colnames(datatest)))

#Visit by specific assignment:
vbtinq(colnamevbt, c(2, 3, 1, 1))

#Traversal of the second layers:
vbtinq(colnamevbt, c(2, -1, 1, 1))

#Invalid assignments in 1st and 3rd layers:
vbtinq(colnamevbt, c(4, 3, 7, 1))
