When I download hexbin from Bioconductor and then use library(hexbin) I get
the message that I should download the newest version.
The old version is fine for what I want to do, except that I would like to
add some points to the plot.
e.g. an MA plot with controls highlighted
plot(MA$A[,1],MA$M[,1],main="MA plot")
points(MA$A[mypoints,1],MA$M[mypoints,1],col=2)
I want to replace the first plot command with hexbin (so I can actually
visualize the dense region of the plot), but I want to be able to add my
points to the plot.
plot(hexbin(MA$A[,1],MA$M[,1]),main="MA plot")
points(MA$A[mypoints,1],MA$M[mypoints,1],col=2)
does not give an error message. But the points do not show up.
If the new version can do this, could someone please point me to the
download site.
Thanks,
