Font in JavaGD() & pdf()
Dear r-helpers,
When I do an xYplot and display the result in a JavaGD() window, the
font is sans-serif (presumably Helvetica). When I send the figure to
a pdf, I get a serif font (presumably times). How do I insure that
the font in the pdf is indeed the default sans serif?

glm and plot.effects
Dear R-helpers,
I don't see a difference between the following two plots of effect
objects, which I understand should be different. What am I missing?

Incompatability of lme4 and Matrix packages
I just installed R 2.4 on a windows machine and installed the lme4 package
version 0.9975-1. Unfortunately this version requires the 0.9975-2 version of
the Matrix package which I cannot seem to find. It seems the newest version I
can find is 0.9975-1. Is there somewhere I could find this newer version.

ggplot2::qplot() -- arbitary transformations of coordinate system?
Hi,
Does anyone know how to do a coord_trans() in which the y-axis is
tranformed into (for example) -1000/y?
Thanks,

Bug in xYplot() with method = 'filled bands'
Dear r-helpers,
I have been bitten by a cryptic comment in the help page for xYplot().
Here is some code from Madeline Bauer, one of the authors, which is
essentailly the code on the help page for xYplot():
# This example uses the summarize function in Hmisc to
# compute the median and outer quartiles. The outer quartiles are
# displayed using "filled bands"

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?

Packages 'effects' loads 'name' which conflicts with 'lme4'
Hi,
I would like to use the effect() function (actually a slightly modified version of it) on the output of the lmer() function in the lme4 package. But the effects package requires the nlme pacvkage, which is incompatible with lme4. Workaround?

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)

Concave Hull
Dear Friends,
Here is an algorithm for finding concave hulls: http://get.dsi.uminho.pt/local/
Has anyone implemented such an algorithm in R?
RSiteSearch('concave hull') didn't reveal one (I think).

Package simex
Dear R-helpers,
It is not clear to me how you get measurement.error SD when you have a
single dataset, and it is not clear to me how sensitive SIMEX is to
errors in the estimates of measurement error.
Could someone please point me to the relevant literature?

ANOVA between & within variance
hi,
is there an option to calculate the 'within' & 'between' group variances
for a simple ANOVA (aov) model (2 groups, 1 trait, normally distr.) ?
or do I have to calculate them from the Sum Sq ?
thanks for your time and greetings,
gregor

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,

Why does lmList() fail when lm() doesn't?
Dear r-helpers,
Can anyone suggest why lm() doesn't complain here:
summary(osss.lm1 <- lm(logOdds ~ c.setSize %in% task, data = osss))
whereas in package:nlme (and in package:lme4)
osss.lmL <- lmList(logOdds ~ c.setSize %in% task | subj, data = osss)
# Error in `contrasts<-`(`*tmp*`, value = "contr.treatment") :
