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)
Object of class cycle
(if not, coerced)
A cyclist
Integer governing the size of the partition assumed, with
default NULL
meaning to use the largest element
Boolean, with default TRUE
meaning to unlist if
possible
Boolean, with default TRUE
in function
shape_cyclist()
meaning that the shape of the identity is
“1” and FALSE
meaning that the shape is NULL
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.
