[R] Varying x-axes ticks

Please consider the following:
plot(0:1, axes=F)
axis(1)
If you read the help page for "axis" and work the examples there,
you may be able to figure it out. Hint: Develop a function, say, fn,
to shrink 25-104 to 25-50 leaving x < 25 unchanged. Then the following
should work for you:
plot(fn(x), y, axes=F) # where x and y are the numbers you want to plot.
axis(1, fn(xlabs), xlabs) # where xlabs = numbers for which you want
tick marks and labels
axis(2)
I did NOT TEST this particular piece of code, but I've done things
like this in the past, and they worked.
hope this helps.
