Separate x-axis ticks for panels in xyplot()?
Dear r-helpers,
In an xyplot I have
xyplot(y ~ x | c, groups = g,
scales = list(
x = list(
at = v1,
labels = c('A', 'B', 'C', 'D'),
rot = 45
)
)
)
g consists of two groups. How do I define a different set of x ticks
and labels for the second panel? I'm looking for something like
xyplot(y ~ x | c, groups = g,
scales = list(
x =

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.

How to change col and pch between panels in xyplot
Dear R-helpers,
x <- rep(1:2, 4)
y <- c(2, 4, 3, 5, 1, 3, 2, 4)
w <- factor(rep(1:2, each = 4))
v <- rep(1:2, each = 2, 2)
xyplot(y ~ x | w, groups = v, type = 'b')
How do I tell xyplot to use four colors and four plot characters and
four line types? And how do I set up an appropriate key in each?

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?

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?

How to add the variable name to a qqplot or densityplot in the diagonal of an splom?
splom() doesn't complain here, but writes no names in the diagonal
boxes. What am I missing?
I believe that I need to add something like grid.text(x, ...) to the
diagonal panel, but I don't know how to get it cycle through the
column labels. And should
varname.col = 'blue', varname.cex = 1
be inside the diag.panel() function?

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?

I am looking for an idiom that swaps the elements of df$a and df$b

df2 <- data.frame(a = LETTERS[c(1, 4)], b = LETTERS[c(3, 2)], c = 1:2)

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?

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,
