Book Recommendation
Stephen, I see lots of answers with packages and resources, but not
book recommendations. I have used Introduction to Data Technologies
by Paul Murrell (https://www.stat.auckland.ac.nz/~paul/ItDT/) to teach
SQL and database design and would recommend looking at it as a
possibility.

when installing packages for R on Linux, is it better to use my distro's package manager, or install.packages()?
Distribution package manger, always.

Retirement/archiving of rgdal, rgeos and maptools October 2023
The third report on the R-spatial evolution project has been published.

It links back to earlier blogs and presentations, and focuses on work that
maintainers of R packages and workflows using rgdal, rgeos and maptools
need to put in train now before the packages are archived on CRAN.

To install a new R package, is it better to use Linux Mint's pacakge
manager (e.g. synaptic, apt-get, or similar), or to install it within R
with install.packages("some_new_package")?

Positron as a tool
Just to be clear, Denis, I am not in any way associated with anybody or anything and just read about it on a news feed not from POSIT directly.
I am aware it is based on existing functionality and have used possibly similar editors for other languages. I did try possibly one touted by Microsoft years ago (perhaps what you are referring to) but felt no need to keep using it at the time. What I am

Weird R Studio behaviour...
I think you should also update R to the latest version, as that *might* be
the source of the problem.
Other may be able to give you a specific diagnosis, but updating R is to a
(reasonably, at least) current version is good practice anyway.
Cheers,
Bert

Wish: a way to track progress of parallel operations
Hello,
thanks for bringing this topic up, and it would be excellent if we
could come of with a generic solution for this in base R. It is one
of the top frequently asked questions and requested features in
parallel processing, but also in sequential processing. We have also
seen lots of variants on how to attack the problem of reporting on
progress when running in parallel.

R related tools - GUI
For years I used Deducer (Package Deducer) developed by Ian Fellows.?
This is still available and partially remains mostly functional.? He was
working on a new GUI years ago but appears no longer to be in the
pipeline I think replaced by R-Studio.

Creating binary variable depending on strings of two dataframes
Hi,
consider the following two dataframes:

ShowMessage (second attempt)
Surely someone out there knows how to notify their
Windows users that access to their samba server is
going to be terminated....
Any help will be *greatly* appreciated.

I would like to shut down samba before I begin my
backup routine. Before I do this, I would like to

New users cannot log on, current users okay
I am having a problem with the Samba server that I run. Simply, new users
added to the system cannot log on to the PC's that are controlled from the
Samba server's domain. Users that are already on the system and have been
working for some time seem to be unaffected.
I suspect that the problem may well be related to the 'minor' problem we
experienced with the server the other

IE install with Wine 0.9.12 under Debian Sarge
Has anyone got any Internet Explorer to install (and then hopefully run)
with Wine under Debian Sarge?
I tried all the methods I could find and have not been able to
successfully do this. I even tried wiping out the old ~/.wine dir and
starting fresh, but to no avail. I would appreciate info on this.
Thanks

importing data to SQLite database with sqldf
Hi all,
I am attempting to learn SQL through sqldf...
One task I am particularly interested in is merging separate
(presumably large) files into a single table without loading these
files into R as an intermediate step (by loading them into SQLite and
merging them there).
Taking a step back, I've considered these alternatives:
1) I know if I use straight SQLite commands I might use the

sqldf: issues with natural joins
Hello,
I'm having trouble discovering what's going wrong with my use of natural
joins via sqldf.
Following the instructions under 4i at http://code.google.com/p/sqldf/,
which discusses creating indices to speed joins, I have been only unreliably
able to get natural joins to work.
For example,
> Tid <- c('AES 01-01-02 10:58:00', 'AES 01-01-02 11:53:00', 'AES

New R package sqldf
sqldf is an R package for running SQL select
statements on one or more R data frames. It is
optimized for convenience making it useful
for ad hoc queries against R data frames.
Given an SQL select statement whose tables
are the names of R data frames it:
- sets up the database (by default it transparently
