Awk and Vilno
In clinical trial data preparation and many other data situations, the
statistical programmer needs to merge and re-merge multiple input
files countless times. A syntax for merging files that is clear and
concise is very important for the statistical programmer's
productivity.
Here is how Vilno does it:
inlist dataset1 dataset2 dataset3 ;
joinby variable1 variable2 where ( var3<=var4 ) ;

A really simple data manipulation example
In response to those who asked for a better explanation of what the
Vilno software does, here's a simple example that gives some idea of
what it does.
LABRESULTS is a dataset with multiple rows per patient , with lab
sodium measurements. It has columns: PATIENT_ID, VISIT_NUM, and
SODIUM.
DEMO is a dataset with one row per patient, with demographic data.
It has columns: PATIENT_ID, GENDER.

How do you do an e-mail post that is within an ongoing thread?
That may sound like a stupid question, but if it confuses me, I'm sure
it confuses others as well. I've tried to find that information on the
R mail-group info pages, can't seem to find it. Is it something
obvious?
To begin a brand new discussion, you do your post as an e-mail sent to

Shorewall performance
I have a couple of firewalls that are rather complicated - one has 21
interfaces, and the other has about 50 (there''s some heavy use of
802.1q, they only have half a dozen network cards). They work okay,
but - compiling the rules takes a long time even on the faster
servers, and restarting shorewall-lite takes between 5 and 10 minutes

SPSS data import: problems & work arounds for GSS surveys
I'm using R 2.8.1 on Ubuntu 8.10. I'm writing partly to ask what's
wrong, partly to tell other users who search that there is a work
around.
The General Social Survey is a long standing series of surveys
provided by NORC (National Opinion Research Center). I have

Data cleaning & Data preparation, what do R users want?
R has a very wide audience, clinical research, astronomy, psychology, and
so on and so on.
I would consider data analysis work to be three stages: data preparation,
statistical analysis, and producing the report.
This regards the process of getting the data ready for analysis and
reporting, sometimes called "data cleaning" or "data munging" or "data
wrangling".
So as

Using two (...) in a function
Hello R-Helpers,
I am not sure if it is a very simple question but I would like to use two
(...) in a function, for example,
this is a script where I would like to input the variable names (in one of
the (...)) and the variances associated to those variables which are not
calculated in the script because there is a specific software to calculate
it (the other (...))

Efficient selection and alteration of dataframe records
Hi All,
I am writing a simulation that examines the effects of species
extinctions on ecological communties by sequentially removing
individuals of a given species (sometimes using weighted probabilities)
and replacing the lost individuals with species identities randomly
sampled from the remaining individuals. Thus I use two dataframes. One
contains all the individuals and their species

8 char labels in read.spss
I was wondering why it is possible to read long labels from the CVS
files but not from the SPSS files.
I did not have much time to search for the code but I found:

SPSS long variable names
Hello guys I am new to this list and for R too.
I am wondering if there is a patch for the SPSS reading code on the
foreign package, in order to be able to read long variable names.
Right now read.spss() just trunc the names to 8 characters.
Or if someone could help me on other way:
I have to process everyday a lot of SPSS Syntax Files and Dat files
that come from one system that can only export

SPSS 11.5
Hi!
My wife needs the good, old SPSS 11.5 installed on Linux. Thanks to this forum, Wine is running as it should. But now I have a problem with SPSS: After starting the program (installation was no problem), I just see the frame of the window (which is empty - I can see the window behind it), and the first dialog screen in the middle of it.

How to learn abut what is in the samba ldap directory
I once upon a time worked with DAP and watched LDAP being created as
something that actually could work...
Showing my age here.
What little I have done with LDAP has been very clearly delineated so
that I knew what was being done. Here, with Samba, and I guess
actually, it is AD, I have not found that. Yet. But there are always
tools.
So I am looking at: phpLDAPadmin
