Hi all I want to apply different colors on a simple plot: If I type par(br="gray") before a plot it puts all the image in gray but (imagine I run a simple plot) want to let the centrall box (where the dots are plotted) in white or image in lightblue. Can anyone guide me to apply this second step (make the box where the series are plotted in different colours). Thanks in advance. [[alternative HTML version deleted]]
If I understand what you want correctly, you'll probably want to use the
"col" argument in whatever base graphics function you're using,
rather than
changing something in the graphical parameters. For example, if I wanted to
add red points to an existing plot, I would use something like
points(c(1:10), col="red")
Or, if I wanted to generate a barplot using a shading color other than gray,
barplot(c(1:10), col="steelblue")
Does that answer your question?

Hi Jim, Last question. I´m using a spanish version (there are some documents on how constructing good plots and I have found them althought not very intuitive...) I will read them in a next days. Only if you know the way. Imagine I have made a plot like plot(x,y) and I use labels (on each cross point appears a name) but they appear on the dot ¿Do you know some way to show the label below the dot? there is some way to indicate the program try to not to overlap labels (if they are very near?) Happy nice wekend all¡¡¡ 2010/1/29 Jim Lemon <jim@bitwrit.com.au>> On 01/29/2010 10:08 AM, Jose Narillos de Santos wrote: > >> Hi Jim your suggestion doesn´t work properly.
