readPNG gives warnings and doesn't execute sample code from help files
Dear all,
I noticed in the latest R version (R.2.12.1) that the readPNG gives
following warning when running the example code in the help file (or
when using any other png for that matter) :
50: In rasterImage(img, 1.2, 1.27, 1.8, 1.73) :
Per-pixel alpha not supported on this device
No picture is shown, and code I used to be able to run, doesn't run any more.

Sweave choking on \\ in filename
Dear all,
Sweave chokes when using "\\" in the path to the Rnw file. Using "/"
works fine. The problem is that Eclipse+StatET uses "\\" in the
filename.
And example of the error, traceback and sessionInfo are given below.
Best regards,

Rectangle height in lattice xyplot key
Dear All
I have a problem with the height of the boxes in the key in the following.
(The text is over 2 lines to accentuate the problem of no space
between the rectangles.)
Is there an easy way to put a space between the rectangles; size
controls the width but there appears to be nothing for the height?

ggplot2, geom_hline and facet_grid
Hi
I have a long data set on which I want to do Bland-Altman style plots for each rhythm type
Using ggplot2, when I use geom_hline with facet_grid I get an extra set of empty panels.
I can't get it to do it with the "Diamonds" data supplied with the package so here is a (much abbreviated) example:

Legend on plots when using Cairo
Dear all,
I am trying to use the Cairo package to avoid some X11 issues and it
works very well. However, when I want to add a legend to my plots, I
receive an error message from Cairo:

This works fine. But:

User input after opening graphing device
If I run the following:
> windows()
>
> bringToTop(-1)
>
> interactive()
[1] TRUE
>
> run <- readline(prompt = "Continue (Yes = 1, No = 2):")
Continue (Yes = 1, No = 2):
> dummy <- 1
> run
[1] ""
it does not allow user input though the session is interactive (it jumps right over the readline command).
It would be great

Change font size in Windows
My day for dumb questions. How do I increase the type size in the Rgui console in Windows? (R-2.13.0, Windows 7)
It looked to me that I just needed to change the font spec in Rconsole but that does not seem to be working.
The R FAQ for Windows has a reference in Q3.4 to changing fonts, (Q5.2), but I don't see anything relevant there.
Rconsole originally was:
font = TT Courier New

ctree and survival problem
Dear all,
I was intrigued by the ctree command and wanted to check it out. I first ran the demo with example(ctree) and did get the survival graphs in the end. Upon doing this with my own data and yielding a "Invalid operation on a survival time" I tried to rerun example(ctree) and now I also get "Invalid operation on a survival time" after the example runs plot(GBSG2ct)...

strange problem with strptime and date variable
Hello all,
I am manipulating a large database with 70,000 records. "strptime" generates
a date variable but R treats some of the values as NA. I attach a simple
example below.
I have spent hours on this problem. Any hint would be greatly appreciated.
Many thanks,

Simple order() data frame question.
Clearly, I don't understand what order() is doing and as ususl the help for order seems to only confuse me more. For some reason I just don't follow the examples there. I must be missing something about the data frame sort there but what?
I originally wanted to reverse-order my data frame df1 (see below) by aa (a factor) but since this was not working I decided to simplify and order by

R crashes with 'nlme' and corStruct
Hello,
I would like to fit correlation structures with nlme, but R crashes.
My data is similar to the "growth of orange trees" example from Pinheiro and
Bates (2000),
but data are not equally spaced in time, as the last observation is taken
after 6 days ( and not 2 as the others).
This is the code I'm using:
