How do I draw non-square matrices with image() and get the axes right?
Try 1: a <- matrix(rnorm(100),20,5) image(1:20,1:5,a,asp=1,xlab="label here") # No good because the axes don't touch the image Try 2: image(1:20,1:5,a,asp=1,axes=F,xlab="label here") axis(side=1,pos=0) # No good because the x axis label is floating far from the x axis. Try 3: image(1:20,1:5,a,asp=1,axes=F,xlab="",ylab="") axis(side=1,pos=0) # No good because the x axis label is absent.
