[R] plot control

Dear R gurus,
I'd like to plot a distribution with the tickmarks always at the quantiles
of the y-axis, as opposed to the quantiles of the distribution I am
plotting. plot seems to place these ticks based on some calculations that I
cant see (?plot doesnt show the innards of plot).
Below is some functional code, but the tick marks are placed unattractively
since I am referencing the quantiles of the distribution. I'd ideally like
the tickmarks to be able to reference fixed points on the y-axis and the
show the associted values.
I'd be very grateful for ideas, suggestion and leads.
# some code
plot(x, mat[,1], col = "blue", yaxt = "n", ylab="")
axis(2, at = sort(mat[,1])[c(0.25*l,0.5*l,0.75*l)],
labels = round(sort(y1)[c(0.25*l, 0.5*l,0.75*l)],2))
points(x, mat[,2], col = "red")
axis(4, at = sort(mat[,2])[c(0.25*l,0.4*l,0.75*l)],
labels = round(sort(y2)[c(0.25*l, 0.5*l,0.75*l)],2))
