Lists of Polynomials
Create and manipulate lists of polynomials.
polylist(...) as.polylist(x) is.polylist(x)
... |
R objects, polynomials or capable of coercion to polynomials. |
x |
an R object. |
polylist takes a list of arguments, tries to convert each into
a polynomial (see polynomial), and sets the class of the
list to "polylist".
as.polylist tries to coerce its arguments to a polylist, and
will do so for arguments which are polynomials or lists thereof.
is.polylist tests whether its argument is a polylist.
