ezplot: Easy Function Plot

Description

Easy function plot/wo the need to define x, y coordinates.

Usage

ezplot(f, a, b, n = 101, col = "blue",
       grid = TRUE, gridcol = "gray", fill = FALSE, fillcol = "lightgray",
       xlab = "x", ylab = "f (x)", main = "Function Plot", ...)

Arguments

f

Function to be plotted.

a, b

Left and right endpoint for the plot.

n

Number of points to plot.

col

Color of the function graph.

grid

Logical; shall a grid be plotted?; default TRUE.

gridcol

Color of grid points.

fill

Logical; shall the area between function and axis be filled?; default: FALSE.

fillcol

Color of fill area.

xlab

Label on the x-axis.

ylab

Label on the y-axis.

main

Title of the plot

...

More parameters to be passed to plot.

Value

• Plots the function graph and invisibly returns NULL.

Details

Calculates the x, y coordinates of points to be plotted and calls the plot function.

If fill is TRUE, also calls the polygon function with the x, y coordinates in appropriate order.

Examples

fun <- function(x) x * cos(0.1*exp(x)) * sin(0.1*pi*exp(x))
ezplot(fun, 0, 5, n = 1001, fill = TRUE)
