Re: [R] A graph with a positive y-axis intercept
Dear Sarah and A.K., Yes, both your suggestions give me exactly what I wanted. Thank you kindly.

Re: [R] A graph with a positive y-axis intercept
HI, I guess you wanted to change the scale of Y-axis: plot(X,Y,ylim=c(0,25)) A.K. - Original Message - From: "Lekgatlhamang, lexi Setlhare" To: "r-h...@stat.math.ethz.ch" Cc: Sent: Thursday, July 19, 2012 5:31 PM Subject: [R] A graph with a positive y-axis intercept Dear all, I have a challenge with a supposedly simple graph (a scatter). I wanted to use R to create a plot/graph with a positive y-axis intercept but it does not seem to give me what I expect to see. As an example, I used the following values > X<- c(0, 4, 8, 11) > Y<- c(8, 12, 15, 22) then I used the plot function in the base package > plot(X, Y) This gave me a graph which might be mistaken to be starting from the origin, and yet, using the same numbers in Excel, and plotting them using the scatter option, I get a graph which clearly has a positive y-axis intercept.

Your question is not entirely clear to me, but I think you might want: plot(X, Y, xlim=c(0, 25), ylim=c(0, 25)) Sarah On Thu, Jul 19, 2012 at 5:31 PM, Lekgatlhamang, lexi Setlhare wrote: > Dear all, > > I have a challenge with a supposedly simple graph (a scatter).
