Polyn: Polyn Class

In tolBasis: Fundamental Definitions and Utilities of the Time Oriented Language (TOL)

Description

Implements the TOL grammar "Polyn" in R.

Usage

# Creates a new Polyn Object
Polyn(coeffs, base=0)
## S3 method for class 'Polyn'
as.character(x, ..., backward="B", forward="A")
## S3 method for class 'Polyn'
print(x, ...)

Arguments

coeffs	a vector of coefficients
base	the degree of the first coefficient
x	a Polyn object
...	further arguments
backward	the character to print the lag operator
forward	the character to print the inverse lag operator

Value

The method print prints the expression of the Polyn object and returns it.

Examples

# Creates lag polynomial: 1+B^2
p <- Polyn(c(1,0,1)) 
# Gets the Polyn object expression as in TOL
as.character(A+B, forward="F")
# Prints the Polyn object as in TOL
print(A+B, forward="F")
