shape | R Documentation |
Returns the shape of a permutation. If given a word, it coerces to cycle form.
shape(x, drop = TRUE,id1=TRUE) shape_cyclist(cyc,id1=TRUE) padshape(x, drop = TRUE, n=NULL) shapepart(x) shapepart_cyclist(cyc,n=NULL)
x |
Object of class |
cyc |
A cyclist |
n |
Integer governing the size of the partition assumed, with
default |
drop |
Boolean, with default |
id1 |
Boolean, with default |
Function shape()
returns a list with elements representing the
lengths of the component cycles.
Function shapepart()
returns an object of class
partition
showing the permutation as a set partition of
disjoint cycles.
Function shape()
returns the lengths of the cycles in the order
returned by nicify_cyclist()
, so not necessarily in increasing
or decreasing order.
