NostalgiR (version 1.0.2)

nos.xyplot: nos.xyplot text-based scatter plot.

Description

Plots a text-based scatter plot, with the option of having a regression line, or a linear interpolation of the points.

Usage

nos.xyplot(x = 1:length(y), y, xlab = NULL, ylab = NULL, ratio = 0.25, width = round(options()$width * 0.8), height = round(ratio * width), pch = c("o", "~"), type = "p")

Arguments

x

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

y

A numeric vector containing the y-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.

ylab

Label of the y-axis of the plot.

ratio

Coefficient that controls the aspect ratio of the plot.

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 the x and y coordinate points, and the second symbol is for the interpolation or regression line.

type

One of the values in the set c('l','p','r','lp','pr'). Type 'l' plots a linear interpolation, type 'p' plots the x and y coordinates as points, type 'r' plots a linear regression line, type 'lp' plots x and y coordinates along with a linear interpolation, and type 'pr' plots x and y coordinates along with a linear regression line.

Examples

## Plot 10 correlated points
x <- 10*runif(10)
y <- x + rnorm(10)
nos.xyplot(x,y,type='p',xlab='x',ylab='y')

## Plot 10 correlated points with a regression line
x <- 10*runif(10)
y <- x + rnorm(10)
nos.xyplot(x,y,type='pr',xlab='x',ylab='y')

## Plot 10 correlated points with a linear interpolation
x <- 10*runif(10)
y <- x + rnorm(10)
nos.xyplot(x,y,type='lp',xlab='x',ylab='y')
