Dear all, I am trying to use hexbin and read the very interesting article on grid ( http://www.ci.tuwien.ac.at/Conferences/useR-2004/Keynotes/Murrell.pdf ) and am hoping for some advice from more experienced users of hexbin.
I am trying to visualise a data and fit a straight line trough it. For example, here is how I would do it in the usual way # simulate data x <- rnorm(1000) y <- 5*x + rnorm(1000, sd=0.5) plot( x, y, pch="*" ) abline(0, 1, col=2) And here is my failed attempt at fitting the "abline" on hexbin library(hexbin); library(grid) plot( hexbin( x, y ), style = "nested.lattice") grid.move.to(0.2,0.2) grid.line.to(0.8,0.8) I realise that grid.* is taking plotting coordinates on the graph but how do I tell it to use the coordinates based on the data values ? For my real data, I would like lines with different slopes and intercepts. I am using the hexbin version 1.2-0 ( which is the devel version ), R-2.0.1 and Fedora Core 3. Many thanks in advance.
