powerplot: Plot of Power Functions

Description

This function plots powers of a variable on the interval [0,10].

Usage

powerplot(expr="x^2", xlab="x", ylab="y")

Arguments

expr

Functional form to be plotted

xlab

x-axis label

ylab

y-axis label

Value

A plot of the given expression on the interval [0,10].

Details

Other expressions such as "sin(x)" and "cos(x)", etc. could also be plotted with this function, but results are not guaranteed.

Examples

Run this code
# NOT RUN {
   oldpar <- par(mfrow = c(2, 3), mar = par()$mar - c(
        1, 1, 1.0, 1),  mgp = c(1.5, 0.5, 0),  oma=c(0,1,0,1))
#    on.exit(par(oldpar))
    powerplot(expr="sqrt(x)", xlab="")
    powerplot(expr="x^0.25", xlab="", ylab="")
    powerplot(expr="log(x)", xlab="", ylab="")
    powerplot(expr="x^2")
    powerplot(expr="x^4", ylab="")  
    powerplot(expr="exp(x)", ylab="")
par(oldpar)
# }
