I didn't even remember grid()...
If you look at it, you see that it's a basic interface to abline. ->
abline(h= y.vec, v = x.vec, col = .., lty =.., lwd = ...)
2nd) solution, more closely linked with asking for
``grid where the labels are'' : Use the "tck" par() :
axis(1, at=1:10, tck = 1)
axis(2, at=2*(1:5), tck=1)
However, I don't think you can set `col', 'lty',... of these
[--> Do we need more par()s , such as col.tck, lwd.tck, lty.tck ,
or at least new axis arguments ? Paul ?
