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.

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:

lapply and paste
I have a list of suffixes I want to turn into file names with extensions.
suff<- c("C1", "C2", "C3")
paste("filename_", suff[[1]], ".ext", sep="")
[1] "filename_C1.ext"
How do I use lapply() on that call to paste()?
What's the right way to do this:
filenames <- lapply(suff, paste, ...)
?
Can I have lapply()

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.
When I try to install a package, I get the following problem:

updating columns using other column as reference
Dear R-gurus,
Just supose I have a dara.frame that looks like
myDF<-read.table(stdin(),head=T,sep=",")
codID,namesp,k1,k2,k3,k4
1,spA,2,5,6,3
2,spB,4,5,4,6
3,spC,2,1,5,6
4,spC,5,4,3,2
5,spD,1,2,3,4
6,spE,2,4,3,1
I need to update the columns k1-k4 with the namesp, but
considering the math between Kx and codID.
My desired output must looks like:
codID,namesp,k1,k2,k3,k4

argument names inside a function?
Is there a way I can get the names of the arguments passed to a
function from within a function?

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

Problem with subset() function?
Hi all,
Can anyone explain why the following use of
the subset() function produces a different
outcome than the use of the "[" extractor?
The subset() function as used in
density(subset(mydf, ht >= 150.0 & wt <= 150.0, select = c(age)))
appears to me from documentation to be equivalent to
density(mydf[mydf$ht >= 150.0 & mydf$wt <= 150.0, "age"])

Always via logical expressions. In this case you can use the logical expression
myDF$b != "0"
to give you a vector of TRUE/FALSE
