plotScatterM: Scatter plot matrix

In bgovaerts/LMWiRe: Linear Models for Wide Responses

Scatter plot matrix

Description

Produces a scatter plot matrix between the selected columns of the outcomes matrix Y choosing specific colors and markers for the design factors on the upper and lower diagonal.

Usage

plotScatterM(
  Y,
  cols,
  design,
  labelVector = NULL,
  title = "Scatterplot matrix",
  varname.colorup = NULL,
  varname.colordown = NULL,
  varname.pchup = NULL,
  varname.pchdown = NULL,
  vec.colorup = NULL,
  vec.colordown = NULL,
  vec.pchup = NULL,
  vec.pchdown = NULL
)

Arguments

Y	nxm matrix with n observations and m variables.
cols	A vector with either the column names of the Y matrix to plot (character) or the column index positions.
design	A nxk "free encoded" experimental design data frame.
labelVector	Labels to display on the diagonal. If NULL, the cols names are used.
title	Title of the graph.
varname.colorup	A character with the name of the variable used to color the upper triangle.
varname.colordown	A character with the name of the variable used to color the lower triangle.
varname.pchup	A character with the name of the variable used to mark points for the upper triangle.
varname.pchdown	A character with the name of the variable used to mark points for the lower triangle.
vec.colorup	A color vector with a length equivalent to the number of levels of varname.colorup.
vec.colordown	A color vector with a length equivalent to the number of levels of varname.colordown.
vec.pchup	A pch vector with a length equivalent to the number of levels of varname.pchup.
vec.pchdown	A pch vector with a length equivalent to the number of levels of varname.pchdown.

Value

A matrix of scatter plots.

Examples

data("UCH")

plotScatterM(Y = UCH$outcomes, cols = c(1:4), design = UCH$design,
             varname.colorup = "Hippurate", varname.colordown = "Citrate",
             varname.pchup = "Time", varname.pchdown = "Day",
             vec.colorup = c("red","blue","black"),
             vec.colordown = c("orange","purple","green"),
             vec.pchup = c(1,2), vec.pchdown = c(15,16))
