Looking up the directory a file is located in
Hello everyone,
This should be an easy question, I think.
I'd like to write a command in a program to set the working directory to
whatever directory the file is currently stored in. Suppose I have a file
called "myRscript.r", and it's stored in "C:\Rprojects\myRscript.r", and it
references other R scripts and data files in the same directory.
If I enter the

What does the "<<-" operator mean?
I've been reading some code from an example in a blog post (
http://www.maxdama.com/ here ) and I came across an operator that I hadn't
seen before. The author used a <<- operator to update a variable, like so:
ecov_xy <<- ecov_xy+decay*(x[t]*y[t]-ecov_xy)
At first I thought it was a mistake and tried replacing it with the usual <-
assignment operator, but I didn't

Suppressing the Intercept in lm() when using a dataframe for the model
It's easy to run a linear regression on a simple model without an intercept
just by doing this:
lm(y ~ x1 + x2 -1)
Is there a similar trick to suppress the intercept when your model is in a
large dataframe and you don't want to write out the names of individual
columns?

Writing dataframes side by side in a file
Is there a quick and easy way to write data frames side-by-side in a csv file
with one column separating them?
I could just fill them with empty rows so they all have the same height,
then cbind them with empty columns in between, but I'm looking for a more
elegant solution, if one exists.
Thanks in advance,
Cliff

Accessing files on password-protected FTP sites
Hello everyone,
Is it possible to download data from password-protected ftp sites? I saw
another thread with instructions for uploading files using RCurl, but I
could not find information for downloading them in the RCurl documentation.
I am using R 2.11 on a Windows XP 32-bit machine.
Thanks in advance,

Prime Factorization
Hi everyone, I have a very quick question:
Is there a ready-made function in R or any R packages to find the prime
factorization of an integer?

New behavior of 'write.csv' append argument?
Dear R users,
I have recently begun to reuse some functions I made several months ago. The
scripts write to a .csv file using the 'write.csv' function with the append
option set to TRUE. This used to work fine, albeit with the warning
"appending column names to file". I upgraded to R version 2.11.0 on OSX
10.5.8 and 'write.csv' will no longer append any files - I get the

Append to csv without header
Hi,
I am writing a function that writes to a csv file for every call.
However, for the subsequent calls, I want to append the data to the existing
csv file without appending the column names again.
I tried searching in the previous posts, but I am stuck with different
errors.
Here is what I am doing (dataF is a data-frame):-

write.csv (PR#7992)
The write.csv() function is currently implemented as
function (..., col.names=NA, sep=",", qmethod="double")

write.table(..., col.names=NA, sep=",", qmethod="double")
}
Surely, it should be

write.csv suggestion
Hello all,
I had some trouble recently with write.csv because I couldn't change one
of the default options. A quick view of the code showed that the
function was not defined in the most optimal way.
Currently,
write.csv <- function (..., col.names = NA, sep = ",", qmethod =
"double")
write.table(..., col.names = NA, sep = ",", qmethod = "double")

Dear R Debug-Team,
in write.csv() it is not possible to set both

since the col.names = FALSE gets overwritten:

Col.names parameter in write.csv (PR#10411)

OS: Windows 5.1.2600 (Windows XP)
Submission from: (NULL) (203.185.215.144)
The col.names=false in the write.csv command does not work as documented.
Attempting to write a vector to a csv file without column headers does not work
as documented.
The col.names=false feature on the write.table command does however work and it
can thus be coerced

Hi,
How can I write the output to an excel (csv) file without printing row names (i.e without breaks). Here is my code:

two small wishes (with code sugegstions) for R-core
Dear R developers,
It would be great if you could implement the two minor code changes suggested below, which would help processing large objects in R.

# Wish no. 1: let [.AsIs return the class AFTER subsetting, not the class of the original object
# Wish no. 2: adjust write.csv and write.csv2 for multiple calls in chunked writing

Why only a "" string for heading for row.names with write.csv with a matrix?
Consider:

> x
Attr1 Attr2 Attr3

Anybody used the above phone with asterisk
I have one working ok for calls, but having a problem with voice mail.
Using either the 'Voice mail function key' or dialing 88 (for my system)
just gets me to Call Terminated
Asterisk CLI shows the error message 'unable to get User name'
My Grandstream works ok, asking for User name, then Password
Any ideas ?

Weird series of errors with dovecot-stable
I'm using the dovecot-stable from 7/30, authenticating against an

minutes.
