png(type='cairo'): point symbols without boarders are not anti-aliased?
Hi,
It seems that anti-aliasing in png(type = 'cairo') is not well
supported for the point symbols without boarders, e.g. pch = 16. The
Cairo package works well, though. You can compare png() with

I tried this on Ubuntu with R-2.14.1 built from source, and I do not get
the segfault problem. (I don't at the moment have a debian binary R, or
I would confirm whether I get the segfault problem.) My sessioninfo() is

semi-transparency not supported in devel R? "alpha" cannot be specified in qplot()
Hi dear all,
In my laptop(ubuntu 11.10 64bit), I maintained a released R (2.14) and a
developmental R, I can specify qplot(..., alpha = ) in R 2.14 , but when I
try to use transparency in developmental R, I got a warning message and the
plot is clearly not I want.
minimal example:

mysterious warning message regarding bytecode...
While running a long script which source()s other scripts I get the
following warning:
Warning message:
In t(object$S[[1]]) : bytecode version mismatch; using eval
I cannot replicate it if I run the sourced files line by line though...
What is that error? And do I care about it? It doesn't seem to
affect my output as far as I can tell.
Thanks!

trouble parsing a date using strptime()
Hi,
I am having a trouble parsing dates using strptime() that I get in the
format of year and week number. The data looks like this "201127" which
means year 2011 and week 27. I would like to graph this using ggplot but
then I get a gap between 201054 and 201101 so I thought I would just easily
convert it.
I tried to use strptime and as.Date and the format string of %Y%W but it

Caret: Use timingSamps leads to error
I want to use the caret package and found out about the timingSamps
obtion to obtain the time which is needed to predict results. But, as
soon as I set a value for this option, the whole model generation fails.
Check this example:

I must admit I don't know all its history but the original data was taken from an OOo spreadsheet that I edited (good bit of copying and pasting and the month variable added by hand in OOo Calc) and, then,saved as a csv file. It was not originally an English language file as far as I can

grImport symbols
Dear list,
I have two questions regarding grid.symbols() in the grImport package.
This package allows you to import a vector graphic in R, and
grid.symbols() can be used to plot the resulting glyph at arbitrary
locations in a grid viewport.
I have tried the code in the grImport vignette, which is most
interesting, however I am stuck with two problems:

ggplot2 dot chart-start at zero
I am trying to create a simple dot-plot in ggplot2 with a solid line from the y-axis to the dot, something I first saw in Cleveland's 1984 book
What I would like is to have the graph start at zero on the x-axis but leave some space on the right side of the plot area.
I assumed that I should be able to do this with expand() in scale_x_continuous() but either I'm wrong or just don't

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

plot betadisper, change of pch
Hello!
After performing an analysis with betadisper, package vegan I would like
to plot the results - so far, so good. But I would also like to "tune" a
little bit the plotting characters, as '+' and 'x' are a little to
similar...

I can't run fix() or edit() anymore. Did I break my system?
I'm running Debian Linux with R-2.14.1. As far as I can tell, the R
packages came from Debian's testing "wheezy" repository. I would like
to know if users on other types of systems see the same problem. If
no, then, obviously, it is a Debian-only issue and I can approach it
from that point of view. And if no other
