andrews_curve: Draw Andrew's Curve

Description

This function evaluates the transformation of the original data matrix for t from -pi to pi, and uses matplot to draw the curves.

Usage

andrews_curve(x, n = 101, type = "l", lty = 1, lwd = 1, pch = NA, xlab = "t", 
    ylab = "f(t)", ...)

Arguments

x

a data frame or matrix

n

number of x-axis values at which f(t) is evaluated

type, lty, lwd, pch, xlab, ylab, ...

passed to matplot

Value

a matrix of coefficients for each observation at different t values
