If I use the following command to plot points:
plot(c(1,2,2,3,3,3), type="p", pch=20, ylab="Y Label",
xlab="X Label", xaxt="n")
there is a large amount of space between the label "X Label" and the
actual x-axis. If I change the xaxt="n" to xaxt="s", the
label "X
Label" don't move at all. Is there a way to get the label "X
Label"
closer to the x-axis when xaxt="n"?
The plot I am generating is going to be included in a paper I am
writing. I can cause the plot to be saved in a PDF file by doing the
following:
pdf("foo.pdf", width=5.5, height=4.25, onefile=FALSE)
plot(c(1,2,2,3,3,3), type="p", pch=20, ylab="Y Label",
xlab="X Label", xaxt="n")
dev.off();
In the resulting file, there is a lot of whitespace around the graph,
particularly between the top line of the plot area and the top of the
page. Since I am including these plots in a paper, I want them to be
as large as possible and not take up any extra space. Is there a way
to get R to draw a plot that goes all the way to the margins of the
print area?

This technote explains the margin area (mar) and how to modify it to control white space around a graphic: http://research.stowers-institute.org/efg/R/Graphics/Basics/mar-oma/index.htm When you have multiple figures on a graphic, you may also want to learn to control the outer margin area (oma), which is also explained. AFAIK, the only way to get the axis label "closer" to the axis is to suppress the actual axis labels and use the mtext command to display alternative text where you want it. For example, look at the blue text in Figure 2B (at the above link) that is between the axis label and the axis. This blue text is at line=2, when the axis labels are at line=3. efg Bioinformatics Stowers Institute "Jamieson Cobleigh" <cobleigh at gmail.com> wrote in message news:7f50836c050901060555b9289d at mail.gmail.com...> If I use the following command to plot points: > > plot(c(1,2,2,3,3,3), type="p", pch=20, ylab="Y Label", xlab="X Label",xaxt="n")> > there is a large amount of space between the label "X Label" and the > actual x-axis.

That worked and gave me enough information so to make it look exactly the way I want. Thanks!

You can do this with the 'mgp' argument to par() (see ?par). For example, I find par(mgp=c(2, 0.75, 0)) (which puts the axis label on line 2 and the axis values on line 0.75) nicely "tightens up" the space around a plot.
