SPLOM or scatter plot matrix is a technique invented by John Hartigan in 1975 used to determine correlation between a series of variables. These scatter plots are organized into a matrix to facilitaet data exploration. Here are some exaples with multiple configurations using the Fisher's Iris data set
{ "broadcast":"true", "colorBy":"Species", "graphType":"Scatter2D", "layoutAdjust":"true", "scatterPlotMatrix":"true", "scatterPlotMatrixType":"both", "theme":"CanvasXpress" }
library(canvasXpress) y=read.table("https://www.canvasxpress.org/data/cX-irist-dat.txt", header=TRUE, sep="\t", quote="", row.names=1, fill=TRUE, check.names=FALSE, stringsAsFactors=FALSE) z=read.table("https://www.canvasxpress.org/data/cX-irist-var.txt", header=TRUE, sep="\t", quote="", row.names=1, fill=TRUE, check.names=FALSE, stringsAsFactors=FALSE) canvasXpress( data=y, varAnnot=z, broadcast=TRUE, colorBy="Species", graphType="Scatter2D", layoutAdjust=TRUE, scatterPlotMatrix=TRUE, scatterPlotMatrixType="both", theme="CanvasXpress" )
