scatter.ade: Scatterplot

Description

Draw a scatter or a bubble plot

Usage

scatter.ade(x, y=NULL, group=NULL, z=NULL, data=NULL, vnames=NULL,
            main=NULL, xlab=NULL, ylab=NULL, glab=NULL, zlab=NULL,
            legendon="topright", xlim=NULL, ylim=NULL, zlim=NULL,
            lwd=1, cex=1, pch=16, lty=1,
            xticks=NULL, yticks=NULL, zticks=NULL,
            col=NULL, tcol=NULL, bgcol=NULL, lcol=NULL, alpha=NULL,
            fitline=0, wall=0, v=NULL, h=NULL, diag=FALSE, span=0.75)

Arguments

x

• a numeric vector of x coordinates for the points

• a character string with the name of the x variable in the data.frame

• a formula y~x, y~x+group or y~x+z+group

y

• a numeric vector of y coordinates for the points

• a character string with the name of the y variable in the data.frame

group

• a factor to group the points

• a character string with the name of the group variable in the data.frame

z

• a numeric vector for size of the points

• a character string with the name of the size variable in the data.frame

data

data.frame if used character string for (x,y,g,z) or formula

vnames

a vector of character strings with the names of groups in the legend

main

an overall title for the plot

xlab

a title for the x axis

ylab

a title for the y axis

glab

a title of the legend

zlab

a title for the z in the second legend

legendon

a single keyword from:

• "bottomright"

• "bottom"

• "bottomleft"

• "left"

• "topleft"

• "top"

• "topright"

• "right"

• "center"

• "none"

This places the legend on the inside of the plot frame at the given location. To locate 2 legends you can give a vector of 2 keywords.

xlim

the x limits (x1, x2) of the plot

ylim

the y limits (y1, y2) of the plot

zlim

the z limits (z1, z2) for the size of points

lwd

the line width

cex

character (or symbol) expansion: a numerical value, dont work if z is given

pch

plotting "character", i.e., symbol to use. This can either be a single character or an integer code for one of a set of graphics symbols. 15, 16, 17 working well with given z.

lty

the line type

xticks

the number of ticks on the x axis or a vector of exact ticks

yticks

the number of ticks on the y axis or a vector of exact ticks

zticks

the number os Symbols in the z legend or a vector of values for the Symbols

col

a vector of colors for the points for each group

tcol

color of the text in whole plot

bgcol

the background color for plot dekoration

lcol

color for the lines in plot, a vector of colors is possible

alpha

a parameter in [0, 1] for semi-transparency of points

fitline

a number between 0 and 3 to fit:

• 0. not fit

• 1. a lm regression line

• 2. a loess local regression line

• 3. a pylinomial regression line

wall

a number between 0 and 6 for selection the dekoration style of the plot.

v

the x-value(s) for vertical line(s).

h

the y-value(s) for horizontal line(s).

diag

logical asking whether to plot a diagonal line

span

the span parameter for lowess curve fit (only if fitline=2)

Examples

x<-rnorm(1000)
y<-rnorm(1000)
z<-rnorm(1000, 3)
g<-round(runif(1000))
# plot vs ID
scatter.ade(x, vnames=c("blue","red"), alpha=0.25, fitline=2, wall=0, lwd=2, col=4)
# Scatter plot
scatter.ade(x, y*x, g, vnames=c("blue","red"), alpha=0.25, wall=2)
# bubble plot
scatter.ade(x, y, g, z, vnames=c("blue","red"), alpha=0.25, zticks=c(1,2,3,4,5), wall=3)
