Boxplot, formula interface, and labels.
I have data I'd like to plot using the formula interface to boxplot.
I call boxplot like so:
with(mydata, boxplot(count ~ geno * tissue))
I get a boxplot with x axis labels like "wt.kidney". I would like
to change the '.' to a newline. Where is this separator configured?
Thanks,
-Ed

ggplot inside function doesn't plot
I don't really understand. I mean, I understand the solution is
print(ggplot(...)). But why is that required in a function and not at
the console?
Shouldn't I be able to rely on what I do at the console working in a
script? Is this inconsistent behavior by design?

mybp <- boxplot(count ~ geno * tissue, data = mydata, plot = FALSE)
mybp$names <- gsub("\\.", "\n", mybp$names)
bxp(mybp)
See ?boxplot for details.
Best,

Boxplot, formula interface, and labels.
Just change the separator:
data(Titanic)
Titanic.df <- as.data.frame(Titanic)
boxplot(Freq~Class*Sex, Titanic.df, cex.axis=.6, sep="\n")
See attached .png.

Exporting to text files
I have dose response data analyzed with the package 'drc'.
'summary(mymodel)' prints my kinetic parameters. I want
that text in an ASCII text file. I want to get exactly what I
would get if I copied and pasted from the terminal window.
I've read the documentation on data export to text files here:

Broken R
Hi, I am running Debian Sid. I am having
trouble with the R packages.
Executing 'help()' or 'demo()' launches 'most' with no text.
'help.start()' works properly.

help with regexp
Dear list memebers,
I am stuck with using regular expressions.
Imagine I have a vector of character strings like:
test <- c('filename_1_def.pdf', 'filename_2_abc.pdf')
How could I use regexpressions to extract only the 'def'/'abc' parts of these strings?
Some try from my side yielded no results:

[PATCH v2] v2v: disk: strip only common extension (RHBZ#1365005)
In disk input mode, to determine the guest name strip the extension from
the filename only if it's a very well extension for disk images.

A list of data frames and a list of colnames.
I have a list of file names, and a list of data frames contained in those files.
mynames <- list.files()
mydata <- lapply(mynames, read.delim)
Every file contains two columns.
> colnames(mydata[[1]])
[1] "Name" "NumReads"
> colnames(mydata[[2]])
[1] "Name" "NumReads"
I can set the colnames easily enough with a for loop.

lists and rownames
I'm doing some string manipulation on a vector of file names, and noticed
something curious. When I strsplit the vector, I get a list of
character vectors.
The list is numbered, as lists are. When I cast that list as a data
frame with 'as.data.frame()', the resulting columns have names derived
from the original filenames.
Example code is below. My question is, where are these names

Why do I have a column called row.names?
I'm trying to read in a tab separated table with read.delim().
I don't particularly care what the row names are.
My data file looks like this:

data.matrix output is not numeric
I have a data frame full of integer values. I need a matrix full of
numeric values.
?data.matrix reads:
Return the matrix obtained by converting all the variables in a
data frame to numeric mode and then binding them together as the
columns of a matrix.
This does not work.
test.df <- data.frame(a=as.integer(c(1,2,3)), b=as.integer(c(4,5,6)))

subsetting by cell value with a list
I would like to subset by dataframe by matching all rows that have any value
from a list of values. I can get it to work if I have exactly one value,
I'm not
sure how to do it with a list of values though.
This works and gives me exactly one line:
my.df[ which( mydf$IDX==17)), ]
I would like to do something like this:
my.df[ which( mydf$IDX==c(17, 42), ]
Obviously that won't work, but

How to alpha entire plot?
I have two chromatograms I want plotted on the same axes.
I would like the plots to be transparent, so the first chart is
not obscured.
I have tried adjustcolor(..., alpha.f=0.3), the problem is that
my chromatogram is so dense with datapoints that they
overlap and the entire graph just ends up a solid color. The
second histogram still obscures the first.
Consider this example:
col1 <-
