Description

Graphics utiliites.

Usage

xyzPlot(xyz,clrs=NULL,cexText=1.0,xlim=NULL,ylim=NULL,
   xlab=NULL,ylab=NULL,legendPos=NULL,plotType='l') 

Arguments

xyz

A matrix or data frame of at least 3 columns, the first 3 serving as 'x', 'y' and 'z' coordinates of points to be plotted. Grouping, if any, is specified in column 4, in which case xyz must be a data frame.

clrs

Colors to be used in the grouped case.

cexText

Text size, proportional to standard.

xlim

As in plot.

ylim

As in plot.

xlab

As in plot.

ylab

As in plot.

legendPos

As in legend.

plotType

Coded 'l' for lines, 'p' for points.

Details

A way to display 3-dimensional data in 2 dimensions. For each plotted point (x,y), a z value is written in text over the point. A grouping variable is also allowed, with different colors used to plot different groups.

A group (including the entire data in the case of one group) can be displayed either as a polygonal line, or just as a point cloud. The user should experiment with different argument settings to get the most visually impactful plot.
