summary.polynom {PolynomF} | R Documentation |
These function implement methods for summary
, coef
, and
predict
generic funcitons for polynom
and polylist
objects.
## S3 method for class 'polynom': summary(object, ...) ## S3 method for class 'polynom': summary(object, ...) ## S3 method for class 'summary.polynom': print(x, ...) ## S3 method for class 'polynom': coef(object, ...) ## S3 method for class 'polylist': coef(object, ...) ## S3 method for class 'polynom': predict(object, newdata, ...) ## S3 method for class 'polylist': predict(object, newdata, ...)
object |
An object of class polynom or polylist . |
x |
A summary.polynom object to be printed. |
newdata |
A numeric or polynom object. |
... |
Not currently used. |
The summary method for polynom
objects provides information on
the zeros, stationary points and points of inflexion for the object.
For polylist
objects this information is provided for each
polynomial in the list. The result is a list.
For summary.polynom
and summary.polylist
a list of
numeric vectors.
For predict.polynom
and predict.polylist
an object of
the same class as the input argument: either numeric or
polynom
.
For coef.polynom
and coef.polylist
a numeric vector or
matrix, or a list of numeric vectors.
