Dear R Help,I would like to know how to add a colour scale to a matrixplot please. Here is the code that I've used to construct the matrix plot: library(VIM) SpatialPlot<- function(YearxBlock,plot.title){ # Years are columns, Blocks are rows in this matrix YearxBlock<- as.matrix(YearxBlock) # To set margins for the plot: par(yaxt="n", oma=c(4,4,4,4),mar=c(1.5,1.5,1.5,1.5)) # Data coded according to a continuous color scheme, with lowest value "light gray", maximum value as "black", missing values as "white": matrixplot(YearxBlock,col=c("lightgray","black","white"),axes=FALSE) axis(side=1,col="black",at=c(1,4,7,10,13,16,19), labels=as.character(c(1993,1996,1999,2002,2005,2008,2011)),cex.axis=0.8) mtext(text="block",side = 2, line = 1, outer = TRUE, font = 1) title(main=plot.title,adj=0) }
Hi Ross, You can do this with the color.legend function (plotrix).
