Dear R fans,
I would like to create a scatterplot showing the relationship between 4
continuous variables. I thought of using the package "scatterplot 3d" to
have a 3-dimensional plot and then using the size of the symbols to
represent the 4th variable.
Does anybody know how to do this?
Hi Ellen,
The plot is pretty crowded, but you could try this (newdata is your data
frame):
library(plotrix)
size_n_color(newdata$MI,newdata$TD,size=(newdata$EG_18-10.5)/1000,
col=color.scale(newdata$Dstar,1,c(0,1,0),c(0,0,1),xrange=c(60,80)),
yat=c(2.8,3.2,3.6),ylim=c(2.75,3.8),xlab="MI",ylab="TD",
main="Four dimensional plot")
color.legend(2.3,2.52,2.5,2.57,seq(60,80,by=4),
color.scale(seq(60,80,by=4),1,c(0,1,0),c(0,0,1)))
mtext("Size = EG_18",side=1,at=2.83,line=3)
Jim
