This combines both aspects:
## read ?par and parameters xaxs and yaxs
plot(1:10, xaxs = "i", yaxs = "i")
## notice the above means that the point at 1,1 is obscured
## now add a second axis to the bottom (side 1) with ticks at the
## specified locations, and shorter tick marks.
## we also suppress the tick labels.
axis(side = 1, at = seq(0, 10, by = 0.1),
labels = FALSE, tcl = -0.2)
See ?axis for more details on that one.
