Usage

reposition(x, shift = "reset")

Arguments

x

an object of class "dendrogram".

shift

either the character string "reset" (shift the graph so that the height of the farthest leaf from the root is zero), or a numeric value giving the amount to shift the graph along the primary axis.

Value

Returns an object of class "dendrogram".

  plot(x, horiz = TRUE)
