Lattice equivalent of par(mfrow = )
Dear r-helpers,
Does anyone have a straightforward example of putting together three
unrelated (expect for a common y-axis) xyplot() figures in what would
be in base graphics a par(mfrow = c(1, 3)) arrangement?

Failure to produce italics in jpeg
Colleagues,
Using R 2.10.1 in OS X (Snow Leopard), I created JPEG documents that
were intended to include italicized text. In the JPEG versions, the
italics appear in bold-face. The identical code (except for the call
to the device) yields italics in PDF. A minimal example is:
PDF version:
> pdf("plot.pdf")
> plot(1,1)
> mtext(bquote(italic(P) < .(0.005)))

Full_Name: Yan Wong
Version: 2.8.1
OS: Mac OS X 10.4
Submission from: (NULL) (78.149.167.246)
When printing a plot to and svg file, text intended to be in italics is rendered
in bold (svg file viewed using both Safari 3.2.1 and Firefox 2.0.0.9.
For example, try viewing the test.svg file generated by
svg("test.svg", width=4,4,8)
plot.new();

italics help in plot
Part of my script reads:
speciesName <- names(data)[i]
plot(year,depth, xlab="Year",
ylab="Depth(m)",main=expression(italic(paste(speciesName))) )
Unfortunately, this just plots *speciesName *on my graph, not the name of
the species in italics. Any suggestions on how to resolve this?
Thank you

lattice: Set x-axis in italics only
Dear list, I making some box-and-whisker plots in R with vertebrate
data. The x axis are species names that must be in italics. I tried
with the "axis" function but no luck, and it seems that affects both
axes.
Any tip?
Thanks a lot in Advance.

italics and not in main=
R 1.3.0, windows
I've checked archives, and examples in text, mtext, and title.
I am trying to include italicized text in the main title of a figure:
....,
main = "[italics here] species name [italics stop] more plain text"
TIA,
Henry

Italics in plot main title
Hi,
I am drawing several plots and want to have italics in a main title;
this is easy with expression(). However, I want also to add a value to
it, say n_i, that depends on an ith plot. For this I am using paste().
An example: n_i = 10, 20, 30; I want to draw a plot for each i with
the title: "Relative efficiency for sample size n = n_i", where n
should be in italics, and of course n_i

Conditionally swap items in a data frame
df1 <- data.frame(a = LETTERS[1:2], b = LETTERS[3:4], c = 1:2)
I am looking for an idiom that swaps the elements of df$a and df$b
when (e.g.) df$c == 2, resulting in
df2 <- data.frame(a = LETTERS[c(1, 4)], b = LETTERS[c(3, 2)], c = 1:2)

Defining an ex-gaussian PDF
How does one define PDFs as yet undefined in R, such as the ex-
gaussian, the sum of two RVs, one exponential, one Gaussian? The PDF
would then be the convolution of an exponential PDF, dexp(), and a
normal, dnorm().
Kindly cc me in your reply to r-help.
Thanks,

JGR doesn't launch after updating to R 2.2.1
Dear r-helpers,
After updating to R version 2.2.1, 2005-12-20, powerpc-apple-
darwin7.9.0 (from binary), JGR wouldn't launch. I then deleted
everything I could find related to JGR, and reinstalled it from the
latest binary. Both R and JGR are installed in /Applications/

Random Bernoulli sequences with given point-biserial correlation?
Dear R-listers,
Can someone suggest a method for generating a finite Bernoulli
sequence that is likely to have a given point-biserial correlation
with an existing Bernoulli sequence?

Changing appearance of band edges in xYplot()
Dear R-helpers,
I would like the bands in an xYplot() to be gray without dark edges.
I've tried playing around with col.bands, but that seems not to
affect the edges, although changin col.fill does change the fill as I
would expect.
I would appreciate pointers.
