database table merging tips with R
I have not devoted time to setting up ROracle since binaries are not available and it seems to require some effort to compile (see http://cran.r-project.org/web/packages/ROracle/index.html). On the other hand, RODBC worked more or less magically once I set up the data sources.
What is your success using ROracle and why would it be preferable to RODBC ?

creating a derived variable in a data frame
Hello,
I have read through the manuals and can't seem to find an answer.
I have a categorical, character variable that has hundreds of values. I want to group the existing values of this variable into a new, derived (categorical) variable by applying conditions to the values in the data.
For example, suppose I have a data frame with variables: date, country, x, y, and z.
x,y,z are

Large data sets with R (binding to hadoop available?)
Dear R community,
I find R fantastic and use R whenever I can for my data analytic
needs. Certain data sets, however, are so large that other tools
seem to be needed to pre-process data such that it can be brought
into R for further analysis.
Questions I have for the many expert contributors on this list are:
1. How do others handle situations of large data sets (gigabytes,
terabytes)

Help with maps
A few questions about maps...
(1) How can I find a listing of the internal data sets that map() from the maps library contains?
For example, "usa", "county", "state", "nz" all work. Are there any others?
(2) Is there an easier, more generalized way to produce this (http://www.ai.rug.nl/~hedderik/R/US2004/ ) type of plot than this

bottom legends in ggplot2 ?
Has anyone had success with producing legends to a qplot graph such that the legend is placed on the bottom, under the abcissa rather than to the right hand side ?
The following doesn't move the legend:
library(ggplot2)
qplot(mpg, wt, data=mtcars, colour=cyl, gpar(legend.position="bottom") )
I am using ggplot2_0.8.2.
Thanks in advance,

Using R with Hadoop/Hive for Big Data
Hive <http://hadoop.apache.org/hive/> is a data warehouse infrastructure
built on top of Hadoop that provides tools to enable easy data
summarization, adhoc querying and analysis of large datasets data stored in
Hadoop files. It provides a mechanism to put structure on this data and it
also provides a simple query language called QL which is based on SQL and
which enables users familiar with

scatter plot question
Hi R Users,
I have a dataframe like this:
id x rho
A 1 0.1
B 20 0.5
C 2 0.9
...
I want to do a scatter plot of "x" versus "rho" but for each point on the
scatter plot I want the corresponding entry for "id" instead of points. In
STATA I can do so by
twoway (scatter x rho, mlabel(id))
How can I do the same in R? I am sure there is some simple way to do

[patch] sftp-server basepath [yet another]
Hi,
I made this simple path to make sftp-server restricted to a basepath!
This was done because use sshfs [wich base is sftp-server] to allow people
access medias [ cdrom,dvdrom, floppy, usb] from x-terms.
Those x-terms [ diskless] does not have all users, so we share a single user
and a DSA empty passphrase, with some acl scipts at .ssh/authorized keys.
Main usage of this patch is to NOT

The patch modifies configure.ac, so unless you run autogen.sh the configure script isn't modified and that patch doesn't work. Or as an alternative you could simply manually append to config.h:

Anything like dir.choose (similar to file.choose) in R?
Does R have a dir.choose function?
I can use file.choose like this as a kludge to get something like a
dir.choose, but a real dir.choose would be better:
cat("Select one of files in directory to process:\n")
filename <- gsub("\\\\", "/", file.choose())
basepath <- dirname(filename)
Windows provides a lower-level SHBrowseForFolder function to create such

Newbee-Question General Syntax
Hi there!
I´ve started looking into puppet for about one week now, I have to say
that I am NOT a developer, i occasionally write a shellscript or another

picture yet.. I kind of know what i want to do, but at the moment i
don´t realy see how i can accomplish that.. :/

[PATCH v3 0/2] Support drop directories directly from kinit
This patchset applies to klibc mainline.
This patchset introduces the ability to kinit to execute scripts or
executable files present in in the initramfs before switching over to
the root filesystem.
This functionality is implemented in a newly introduced run_parts()
call, which calls scandir() to iterate through files which in then
executes in sequence.
run_parts() is also available as a

[PATCH v2 0/4] Support drop directories directly from kinit
This patchset applies to klibc mainline.
This patchset introduces the ability to kinit to execute scripts or
executable files present in in the initramfs before switching over to
the root filesystem.
It is implemented by first implementing scandir() and alphasort() as
present in POSIX.1-2008 in klibc itself, and then using that as the
basis for iterating and executing files via a run_scripts()

RaislsEdge - where to get latest javascripts ?
To play with RJS I just made a "rake freeze edge". But this copies only the
libs into vendor/rails and any attempt of "rake update_javascripts" fails.
But all the he required javascripts are there, at:
BASEPATH/vendor/rails/actionpack/lib/action_view/helpers/javascripts/
Except of prototype, they seem to have no version number, so I am asking
whether I should take those

[PATCH 4/5] dib: require a Python interpreter
d-i-b 2.0 is written in Python, and thus it passes the information about
the interpreter used for it (sys.executable) to the scripts that need
it; this mechanism replaces the old discovery of what is the default
Python interpreter in the system.
Since we are not Python-based, look for 'python' and use it as default
interpreter, with the --python command line option to set a different
one.
