NostalgiR (version 1.0.2)

nos.density: nos.density text-based plot of a kernel density function.

Description

Plots a text-based of a kernel density function, with the option of plotting the location of the data points along the x-axis.

Usage

nos.density(data, xlab = NULL, ratio = 0.25, bw = "nrd0", kernel = "gaussian", locations = T, width = round(options()$width * 0.8), height = round(ratio * width), pch = c("o", "~"))

Arguments

data

A numeric vector containing the values to be plotted. NA and NaN are allowed, but are removed for the plot. Infinities will cause an error.

xlab

Label of the x-axis of the plot.

ratio

Coefficient that controls the aspect ratio of the plot.

bw

A numerical value or character string to specify the bandwidth used for kernel density estimation. The default setting is 'nrd0', which is the default option in density; see density for other options.

kernel

A character string to specify the type of smoothing kernel used. The default setting is 'gaussian', which is the default option in density; see density for other options.

locations

If TRUE, the location of the data points are plotted along the x-axis. If FALSE, then the locations of the data points are not plotted.

width

Width of the plot in points.

height

Height of the plot in points.

pch

A two dimensional vector of single-character symbols. The first symbol is for data point, and the second symbol is for the density curve.

Examples

## Plot a kernel density function of 10 random standard normal points with
## a Gaussian kernel and with the locations of the data plotted along the x-axis.
data <- rnorm(10)
nos.density(data)

## Plot a kernel density function of 100 random stanard normal points with
## a triangular kernel and without the locations of the data plotted along the x-axis.
data <- rnorm(100)
nos.density(data,kernel='triangular',location=FALSE)
