R help - Oct 2014 - how to ajust y-axis values in plot() ?

Dear helpeRs,
? I want to plot( 11:20 ) in a plot.
?if i just type the code above, the y value? will be from 11 to 20, now i want
the value from a given range like? 0 to 40, how can i do it?
I read ?plot? for a while but? still can't solve it. 
Actually, the qustion is founded when i already plot a plot like plot(11:20) ,
but when i abline(h=40), i found it will go out of the plot even after i used
abline(h=40,xpd=T).
SO, may you help me?

Hello,

Use the argument ylim. See ?par instead of plot.

plot(11:20, ylim = c(0, 40))
abline(h=40)

Hope this helps,

Rui Barradas

See the ylim= argument to plot.default; eg
plot(x, y, ylim=c(0,40))

Also look at ?par and note that plot() and other things often take many of
par's arguments.

Um, yes. A horizontal line at y=40 would not even be inside the plot window if
the plot region is scaled to c(11,20). Where did you expect/want the line to
appear?
