looping over string of frames when importing with 'sqlFetch' from a Microsoft Access database
Dear R-list,
I am trying to import (all) frames from a Microsoft Access database as individual data frames in a fancy loop, but I'm having troubles figuring out how to use the 'sqlFetch' from the RODBS package in a loop (mostly because I can't figure out how to loop over elements (I came from stata)
I would very much appreciate if anyone on the list could help me solve this

Hi, I want to import some data from Access and I am using the following
codes:
testdb <- file.path("c/../db1")

permissions for printing
I have just installed Samba for the following configuration:
AIX 4.2, with NT clients
We are trying to print from clients to unix printers through a Progress
(database) program. On unix, I would identify my destination as "lp -s
-dprinter1". Now, I indicate "//rs6000/printer1". People in our systems

nt acl support = no ???
'llo,
It was suggested that I added "nt acl support = no" to my smb.conf file,
in order to get rid of the "error packet at line 588 cmd=115
(SMBsesssetupX)eclass=2 ecode=2" error.
(Apparently it has something to do with Word's temporary files that are
created with mode 000
which stops it from completing a file save.)
I added this to my smb.conf file

hmmm.. oplock problem on smb craches MS Word ... ?!?
We run samba 2.0.3 and it works fine since several weeks, until these
days...
Since two days I get lots of problems with samba. Oplocks seems to cause
troubles, and it crashes MS Word in such messages: "unrecoverable network
error" indefinitely until Dr Watson (under NT).
We run 2.0.3 with samba as PDC. Quite all the clients run NT 4.0.

OpenOffice Conversion
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
List,
I have a rather unique question, that perhaps can be answered easily
here.I did search google and only came up with one app that does
this exact thing; however, it's an expensive tool. Thusly, not my
cup of tea.
I have need to convert approximately 100 documents in Openoffice's
native format to Microsoft Word's native format.

Controlling unix print queues from PC

I've defined a printer in smb.conf, from a PC (NT 4.0) I can send prints
to it and view the queue OK but I can't manage the queue in any way.

How to set up spooling for a HP JetDirect interface?
I've set up Samba and LPRng for HP printers with
JetDirect cards. It works for one user at a
time. But if the printer is off-line or busy, the
samba client does not get an error message, but
the job gets lost. :( I would like the print
jobs to be spooled on Linux even when there is an
active print job or when the printer is off-line.
Unfortunately I'm not familiar with lpd.

Exporting R graphs
Hi,
I have been a happy user of R for windows for more than a year, however,
recently, I started using linux as my operating system and now I have
practically switched completely. Of course, I still use R with linux,
however, certain nice features of R in windows seem to be missing or
hidden. I need help in basically two points:

Simple plot of values and error bars: Is there an existing function for this
In an OpenOffice.org forum someone asked if it was possible to plot some raw data and then add a line for the confidence interval.
Example at? http://www.graphpad.com/help/Prism5/scatter%20-%20grouped.png
While it may be possible to do this in OOo's spreadsheet program it looks nasty (both to do and the results )

File compare word by word
Is there a utility that compares files word by word, instead of whole
lines or single bytes?
I found that I can simulate this by replacing all the spaces in a file
with linefeeds, then 'diff -B' the results, but that's kind of awkward
and hard to read when differences that matter come up.
(For the record, I tried using OOo's document comparer, converting to
text and using diff,

Integrating R in OpenOffice
Hi All,
A group of about 3-4 of us are looking into the possibility of incorporating R
into OpenOffice's (OO) spreadsheet component (sc) . We wish to use OO's nice
ODBC ability to query a postgresql-based gene expression database thus
populating an OO sc and then use Bioconductor via R to analyse user-selected
parts of this spreadsheet.
We've looked at and compiled and used
