Hi all, I'm trying to plot this two curves in a single cartesian plane, but when I plot the first one, the plot appears with no negative "y" value. When I plot the second curve, it almost does not apear in the graph.
I was trying the plot.window but with no success. Can someone help me with this? If possible, I'd like to plot this curves in a perfect cartesian plane. f = function(x) { x^2 } f2 = function(x) { -x^2 } plot(f,-10,10) abline(h=0, v=0, col = "gray60") curve(f2,col="orange", add=T) Thanks in advanced! *pablo de camargo cerdeira* pablo.cerde...@gmail.com | pa...@fgv.br Phone: +55-(21)-3799-6065 [image: Facebook] <http://www.facebook.com/pablo.cerdeira>[image: LinkedIn]<http://br.linkedin.com/in/pablocerdeira>[image: Google] <http://www.google.com/profiles/pablo.cerdeira> [image: Google Talk/]pablo.cerdeira [image: Skype/]pablocerdeira [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
