fplot: Plot a mathematical function

Description

Plot a mathematical function

Usage

fplot(x, ...)
## S3 method for class 'default':
fplot(x, xlim, ylim, n = 200, args = list(), type = "l", xlab, ylab, ...)

Arguments

x

function-like object to be plotted. For functions, first argument must be numeric and output must be a numeric vector of the same length.

xlim

Limits on plotting window

ylim

Limits on plotting window

n

approximate number of points to use when generating plot

args

additional arguments to f

type

type of plot (see link{xyplot}).

xlab

x-axis label

ylab

y-axis label

...

additional arguments passed to xyplot

Value

• a trellis plot produced by xyplot

Details

fplot uses a simple adaptive algorithm to sample more points in regions where the function is changing rapidly.

Examples

fplot(sin)
fplot(sin,xlim=c(0,4*pi))
f <- function(t) { sin(1/t)  }
fplot(f)
fplot(f,n=500)
