R help - Sep 2013 - plotting issue

Hi R user, 
I was trying to put four figures in a row, in which value of Y axis are similar
but different in X axis. Therefore I wanted to put four figures in row.

To remove y axis for second, thrid and forth figures, I used
[yaxt="n"]. But, I saw that tick mark of Y was found to be missing. I
dont want value in y axis but still I want tick mark. How is it possible?
Example
plot(data1$y, data2$x1, pch=".", cex=1)
plot(data1$y, data2$x2, pch=".", cex=1, yaxt="n")# here I
lost tick marks on y axis: I want tick mark but not text
plot(data1$y, data2$x3, pch=".", cex=1, yaxt="n")
plot(data1$y, data2$x4, pch=".", cex=1, yaxt="n")


Thanks

After plotting with yaxt="n", add the ticks using axis(2, 
labels=FALSE).  (There are many more options to axis, so you have a lot 
of flexibility here.)
