Hello, everyone, I have following csv-file(simplified) as instance:
0.29,2,50 0.32,3,10 0.28,4,71 0.27,1,62 0.53,1,33 0.83,5,100with the first column for x-axis (proportion shared), the second for y-axis (number of shared segments), the shades for 'number of pairs'.
I wonder how to realize that the "number of pairs" are denoted by different shades as shown in the attachment ? So far, I can plot a histogram by these codes, but have no idea how to correctly add information of shades to it.
df<-read.csv(file="c-all-prop-test.csv",head=F,sep=",") require(ggplot2)qplot(x=df[,1],weight=df[,2],geom="histogram",xlab="proportion shared",ylab="number of shared segments",colour = I("darkgreen"), fill = I("blue"))
It seems that d + stat_bin2d() may help. Or maybe heatmap? Could you give me some suggestions? Best regards
