Hi everyone!

This must be a common question but I have not found an answer to it in the
archives yet.

I am producing four plots with par(mfrow=c(2,2)). The x-axis is the same for
all of them but the y-axis is different.
What I would like to do is to have a different range of the y-axis and
different intervals between tick marks. BUT
I would like to have the same number of tick marks and I would like the
y-axis to look the same.

EXAMPLE (with two plots):

plot1:         number of tick marks = 11
                 interval between tick marks = 5 (i.e. tick marks at
0,5,10,15, etc.)
                 range of y-axis = (0, 50)

plot2:         number of tick marks = 11
                 interval between tick marks = 10 (i.e. tick marks at
0,10,20,etc.)
                 range of y-axis = (0,100)


Now I can obtain the values at which there should be tick marks for each of
the above plots. The problem is that
when I plot them with par(mfrow=c(1,2)) I obtain the same graphical height
for each y-axis but the y-axis of plot1
has no tick marks after the value of 50 which looks ugly. I would like to
stretch the 50 of plot1 to where the 100
of plot2 is such that the it looks evenly distributed. But that means that
an interval between tick mark 1 and 2 of plot1
(which is 5) is as long (graphically) as the interval between tick mark 1
and 2 of plot2 (which is 10).

Any ideas on how to do this?

Thanks a lot!!

Cheers,

Hadassa
