S3, S4, namespace
I have encountered an issue which I have been unable to resolve, involving
an S3 generic (print) being declared S4 generic in a package, and the method
being exported. This all works fine - the problem occurs when I try to
import the method to another package.
Here is the bit that works fine. -------------

timestamp on symlink
rsync does not sync the timestamp on symlink (Solaris 8).
It is probablly due to the limitation of Unix implementation
of symlink, but I would like to know why rsync/Unix does not
do this, and what we can do about it. Is the conclusion that
"rsync syncs everything except the timestamp on symlink"?
Why do I need timestamp on symlink? Supposed something stopped
working because something

Icecast not connecting
Hello,
I’m reaching out because our online radio station (sites.up.edu/kdup/) has stopped streaming in the last week - the website itself works fine but when anyone attempts to listen to the live music stream they receive a message that says “cannot connect to the server “icecast.up.edu.” Do we need to update the server, or is this a problem that someone else can take care of? Let me know if I

smbmount/smbumount getting rid of dead connections
I've got a win98 laptop and a linux box. On my linux box, I smbmount
a directory from the laptop. Alas, win98 boxes
crash a lot, and I move the laptop a lot... to and from work.
If the laptop crashes or if I move it with a shared directory mounted
on my linux box, that mount gets "Stuck".... it's
present in /etc/mtab but when I cd to it and do an ls it says:

expressions and paste
I have written a function to plot data which will be used for various different chemistries.
A simplified version is:
plot_data <- function(risk,levels,chem,sd2,measure){
plot(risk, levels,main=paste ("per", sd2, measure, "\n in usual", chem))
}
The problem is with the title.
This works fine if the variable "chem" is just text, but if it is an expression then

legend outside plot area
Hi, please can you help me. When I add a legend to a boxplot it appears inside the plot area, how do you get it into the margins? I have already changed the parameters so there is space for it on the margin on the right hand side of the graph.
Thanks, Emily

Equation as a character string
I'm trying to figure out if it's possible to use a character string as an
equation, e.g:
eqn1string <- "x^2 + x + 5"
Then I want to tell R:
1) that eqn1string is actually an equation (even though it was stored as a
character string), and
2) to apply the equation to a specified value of x (e.g. given x <- 6,
what is the result of the equation).
Thanks in advance for any

converting from courier-imap
Hello. I apologize if there is a simple answer to this question, but I
haven't been able to figure it out. Our people use various clients (pine
4.50 with maildir patch, eudora, messenger, outlook, squirrelmail), and
all of them work with courier-imap. But I've become very interested in
dovecot after reading about it, so I'm trying it out on another server.
The results are mixed.

Split String in regex while Keeping Delimiter
I thought replacing the spaces following instances of +++,++,+,- with "\n" and then reading with scan should succeed. Like Ivan Krylov I was fairly sure that you meant the minus sign to be "-" rather than "?", but perhaps your were using MS Word as an editor which is inconsistent with effective use of R. If so, learn to use a proper programming editor, and in any case

new data frame for loop
I have a data frame with three columns, one coded as a factor. I would like
to separate my data out into separate data frames according to the factor
level. Below is a simple example to illustrate. I can get R to return the
data in the correct format but cannot work out how to get separate data
frames. I am a newcommer to programming in R so am not sure what I am
missing! Thanks, Emily

newbie question on importing and parsing file by row
Hi,
I'm new to R and I have a file with many rows of values. Each row contains a title and values for a contingency table
e.g.
row 1= title 8 0 37796 47
which is a table called 'title'
with values
8 0
37796 47
I would like to know how I can import this using R and for each row calculate a p value using the fisher test. Using each p value I will do multiple a correction.

Changing many csv files using apply?
Dear all,
I have many csv files whose contents I want to change a bit en masse. So far, I've written code that can change them in a for loop, like so:
# Subset of files in the folder I want to change
subset = "somestring"
# Retrieve list of files to change
filelist=list.files()
filelist = filelist[grep(subset, filelist)]

Split String in regex while Keeping Delimiter
Hello List,
?
I have a dataset consisting of strings that I want to split while saving the delimiter.

Some example data:

?leucocyten ? grampositieve coccen +?

I want to split the strings such that I get the following result:

Text Encoding
Dear R-Help,
I am using the RDF package/ R 2.14 with the RDF package to download data
from a website, and then use R to manipulate it.
Text on the website is UTF-8. The RDF package's rdf_load command is
converting it into a different encoding, which converts non-ASCII
characters to unicode codes.
On the webpage/sparql RDF: "4.5µg of cDNA was used"
In R, the RDF triple gives:

object '---' not found
Hi,
I am very new to R and the stats world. I have enjoyed working with R so far
but I have come across an error message in a very simple command that I am
unable to resolve.
I bring data in through excel .csv files and check them to be sure R reads
them correctly and has everything assigned as it is in the excel file. It
looks good. But simple computations are not working

what is the "NOT IN" operator
Good day,
I need to subset a data by removing several rows. I know the %in% operator, i.e.
sub <- mydata[group %in% c("A","B","E","G"), ]
What I need is the opposite, that is remove rows and/or columns. What is the operator for "NOT IN"? I tried (i)! %in% and (ii) ^%in% and both resulted in a "could not find function" error.

Lavaan Package - How to Extract Residuals in Data Values
Hello R Community,
I am using the Lavaan package in R 2.15.0 to analyze data collected from
1200 lakes across North America. My dataset includes 3 continuous
independent variables (LOG_NTL, LOG_PTL, and LOG_SR_A_D) and 1 continuous
dependent variable (BIOVOL) . I have successfully constructed structural
equation models using the Lavaan package (example included below with

glm or transformation of the response?
Hi Dr. Snow,
I am a graduate student working on analyzing data for my thesis and came
across your post on an R forum:
The default link function for the glm poisson family is a log link, which
means that it is fitting the model:
log(mu) ~ b0 + b1 * x
But the data that you generate is based on a linear link. Therefore your
glm analysis does not match with how the data was generated

making package interface with FORTRAN under windows
Dear r-help group,
I am creating a package that has some FORTRAN code under windows. I have
read through "Writing R Extension" but still not so clear about the steps.
Before R CMD build, how can I create a dynamic library and later in my R
function using dyn.load ("xxx.dll") ?
If I already have a .dll file, can I build the package with the dll file
directly ?
Does any one
