Overlay an Exponential Density Function on Histogram

Description

addexp creates a histogram of x and overlays an exponential density function with \lambda = \frac{1}{mean}.

Usage

iscamaddexp(
  x,
  main = "Histogram with exponential curve",
  xlab = deparse(substitute(x)),
  bins = NULL
)

Arguments

x	A numeric vector representing the data to be plotted.
main	(optional) title for the plot.
xlab	(optional) x-axis label for the plot.
bins	(optional) number of bins for the histogram.

Value

A histogram of x overlayed with an exponential density function.

Examples

set.seed(0)
x <- rexp(100, rate = 0.5)
iscamaddexp(x)
iscamaddexp(x, main = "Your Active Title", xlab = "Exponential Data", bins = 20)
