I am trying to come up with a way of shading-in a grid for a simple
pattern
So far I can draw a square where I want but I cannot seem to draw a
complete grid. I am just drawing them along the diagonal!!
Clearly I am missing something simple but what?
Any suggestions gratefully accepted.
Example
#====================================================================
op <- par(xaxs="i", yaxs="i")
plot(c(1, 11), c(1,11), type ="n", xlab="", ylab="")
plot(c(1, 11), c(1,11), type ="n", xlab="", ylab="")
abline(h=2:10, lty=3, col="red")
abline(v=2:10, lty=3, col="red")
Is that what you meant be a "complete grid"?
