Dear all,
today I have writted the following code,
to plot the contents of some matrices I have
plot_shad_f
function(f){
library(ggplot2)
dev.new()
plotdata<-melt(f)
names(plotdata)<-c('x','y','z')
v<-ggplot(plotdata, aes(x, y, z = z))
print(v + geom_tile(aes(fill=z)))
}
I would like to ask your help add a small circle in this plotting. What would
be the easiest way to do that in ggplot2?
Best Regards
Alex
