[R] How can we add a legend to a set of graphs?
Hi, I have a set of 4 graphs and I need to add a legend that is shared by those 4 graphs. This is what I tried: >locator(1) # I placed the cursor in the center of the 4 graphs $x [1] 9.299001 $y [1] 226.3201 >legend(9.3,226.3,"and the rest of the legend arguments")# but the legend didn't show. The legend only appears when I place in inside any of the for plots. How can I place it outside these plots, in the center. Your help will be very much appreciated.

[R] Legend outside plotting area
Hi, I have been trying many of the suggested options to place a legend outside plotting area, including something like this: par(xpd=T, oma=par()$oma+c(4.5,0,1.5,0),mar=par()$mar+c(1,0,1,0) But the aspect of the four plots gets compromised when I change the margin settings. I cannot use mtext because I need to use colors for the text. I tried layout, but wouldn't let me include the legend, only plots. I would appreciate very much some more help.

[R] Manipulating the sizes of multiple screens
Hi, I used split.screen command to creaye 5 screens, 4 screens contain a plot each, the fifth screen is designated to a legend. I am having difficulties setting the dimensions of the screens in a way that would allow me to have the screen dedicated to the legend smaller. I end up with a very awkward aspect at the end: 4 small plots with a big space for the legend. The gend needs to be at the top of the 4 graphs, it's common legend for the 4 graphs. I have tried manipulating the margins of each individual screen, but couldn't obtain the desired aspect. Thank you very much in advance for you help. Best Regards, J You snooze, you lose.

Hi, I need to plot lines in a graph, but when I run the corresponding commands I obtain pixel-like lines, they need to be smooth, is there a way to do this?

Re: [R] How can I obtain smooth lines in graphs?
Thank you Marc, I am using R (version 2.5.0), Windows 2000, and Power Point as the final output and yes, you are right regarding the quality of a PDF file, it's much better than the ones I have tried so far (JPEG, PNG). How can I increase the DPIs?
