match problem by rownames
Hi all,
While dat['a1',] and dat['a10',] produce the same results in the
following example, I'd like dat['a1',] to return NAs.
dat <- data.frame(x1 = paste(letters[1:5],10, sep=''), x2=rnorm(5))
rownames(dat) <- dat$x1

Bug/Error in formatC? (Was: Why doesn't formatC( x, digits=2, format= "g")...)
Hi all
After posting what follows, Duncan Murdoch suggested perhaps a bug
in formatC, or an error on documentation. Any comments?
In particular, bug, error or not, any ideas about how I can
consistently get two significant figures to print?

Adding LaTeX cross-references into Sweave plots
Hi all
I'm using Sweave and LaTeX, and love how they interact.
But here's a different interaction I'm not sure how to achieve; I
hope someone can help. I use a simple example, of course, to
demonstrate.
Suppose in my LaTeX document I have this:
Here is a linear equation:
\begin{equation}
y = -1 + 3 x
\label{EQ:example}

Sweave issue: quotes in verbatim-like output print incorrectly
Hi all
I love Sweave; use it all the time.
But I recently received a new computer, and ever since I
have had a problem I've never seen before.
For example, I place the following in my Snw file:

header=TRUE)

Problem using xtable on an array
Hi all
I know about producing a minimal example to show my problem. But I'm
having trouble producing a minimal example that displays this
behaviour, so please bear with me to begin with.
Observe: I create an array called model.mat. Some details on this:

Building package: What does this message about rcompgen imply?

I'm updating a package for submission to CRAN, and I am getting

it).

Why doesn't formatC( x, digits=2, format="g") doesn't always give 2 sig figs?

digits.
Can someone please explain this to me? These first three give what

rbind with auto-row-named data.frame + list (PR#9346)
There's a problem new to R2.4.0 when rbinding an auto-row-named
data.frame to a list:

Error in attr(value, "row.names") <- rlabs :
row names must be 'character' or 'integer', not 'double'
Works OK with 2 data.frames or 2 lists.

Sweave: pass scale parameter to includegraphics?
Hi all
I'm using Sweave and find it a treat. But one
question:
I use Sweave to create my pictures which are
automatically included into LaTeX. For example,
in the file test.Snw, I may have:
% LaTeX stuff
\begin{figure}
<<fig=true,width=5,height=5>>=
x1 <- seq(1,5, length=10)
x2 <- sin(x1)
plot(x1,x2)

The best way to end up with TIFF {Was: end up with WMF)
Hi all
I posted a couple of days ago about how to end up with wmf files
eventually in R for linux.
The short answer was: you (probably) can't...and don't!
The journal in question also accepts TIFF files, I am told (it's
a physiology journal).
So I adjust my question: What is the best way to get TIFF files
out of R? It can't create them directly as far as I can tell.

White background in PS pictures
Hi all
I am using R to produce postscript pictures via the
postscript command. I have never had any problems...
until now, when I want to inlcude my .ps file is a
LaTeX document *without* a white background. (If
it's important, I'm using the prosper class with
the whitecross option, so the background in blue.)
I would like my .ps file to have a white background.

Two questions
Hi all
Two questions:
1. I note that help for the postscript device claims "The
postscript produced by R is EPS (Encapsulated PostScript)
compatible...". It does not say it is EPS *compliant*.
Indeed, the EPS produced by R includes a \showpage command
which I believe (not that I'm an expert!) non-standard EPS.
My question: Is there any reason why it is EPS compatible,

substitute creates an object which prints incorrectly (PR#9427)
The function "substitute" seems to fail to make a genuine
substitution, although the printed verision seems fine. Here is an
example.
> m <- substitute(Y <- function(x) FUN(x+1),
+ list(Y = as.name("y"), FUN = as.name("sin")))
> m
y <- function(x) sin(x + 1)
> eval(m)
> y

Plotting (mixed) line types and legends

I have a question about plotting line types and
legends. Here's a short piece of code to
demonstrate:

lines(x,y+1, lty=1)

Using xtable with summaries of lm objects

test.lm <- lm( y ~ x )
summary( test.lm )

The best way to end up with WMF files
Hi all
I am doing some stats work for a group of biologists
who require windows metafiles (*.wmf) for their publications.
To create these, I appear to have two choices:
1. Restart my machine in Windows and use savePlot
2. Keep my machine in linux, save as another format,
then convert.
I'd rather stay in linux; but how do I get wmf files? I looked
at using ImageMagick's convert,
