I have a data frame with three columns, type (a factor with two
values: Monolithic and Compositional), size (numeric), and states
(numeric). I want to create a plot where size goes on the x-axis and
states goes on the y-axis. In this plot, I want two lines, one where
the type is Monolithic and
With much help from Chuck Cleland, I was able to get xyplot to
generate the plot I wanted. I'm trying to write a script (that can be
read using source(file)) to create the plots I want and save them to
files.
If I type the following lines into the R (in interactive mode), the
correct plot gets
Thanks, that worked. I see now where it says that in the help for
xyplot, however, it wasn't obvious to me before.

I using lattice to make some plots and I want to make the y-axis on
some of these plots use a log scale. In the following plot:
x - 1:10
y - 2^x
xyplot(log10(y) ~ x)
I get tick marks on the y-axis at 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0. I
would rather have just 3 tick marks at 1.0, 2.0, and 3.0
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

hope it helps,

Similar to my last question, I want to tighten up the spacing and
margins in a plot I am doing with lattice.
Here are the commands I'm using:
data - data.frame(x=c(1:3, 1:3), y=c(1:3, 1:3*2),
cat=c(foo,foo,foo,bar, bar,bar))
xyplot(panel=panel.superpose, y~x, data=data, groups=cat, type=b,
That did the trick.
Thanks!

You can try FreeSnap, a screen capture program for OS X:

Also, why are you running R from an XTerm? There is an OS X native
version of R that might be better integrated with OS X for doing
screen captures:

I just tried using Ctrl-C to do a copy a plot from a graphic window
using the Cocoa version of OS X that you can download from the link
below and I was able to paste the plot into a document.

With some help from those with expertise on this list, I managed to
produce a plot using trellis that looked like I wanted it to look.
Now, I need to take the same plot and make the lines on it color, but
I want to specify the color for the lines myself.
I've managed to make the key use the

I'm using barplot2 to plot some data. Is there any way to determine
the width of the bars in the generated plot? I know that barplot2
returns a list of the coordinates of the center of each bar, but since
there is some white space between each bar, I don't know how to get
the width of each bar.
Thanks. That was all I needed.

Unless you have modified the 'width' argument, the default width is 1.
Thus the sides of the bars are the centers +/- 0.5.
