sqldf hanging on macintosh - works on windows
Have a long script that runs fine on windows (32 bit). When I try to run in
on two different macs (64 bit), however, it hangs with identical behavior.
I start with:
library(sqldf)
This results in messages:

tcktk problem with custom R 2.15.0 build on RHEL5
Hi all,
Please bear with me because I'm not all that familiar with R. I manage a
research cluster that's running Red Hat 5.6 (64-bit), and we recently
installed version 2.15.0 of R for some users. Here's how we built it:
./configure --prefix=/opt/shared/R/2.15.0 --with-tcltk --with-system-zlib --with-system-bzlib --with-system-pcre --with-lapack --enable-R-shlib

Automatic detachment of dependent packages
Dear All,
When one loads certain packages, some other dependent packages are
loaded as well. Is there some way of detaching them automatically when
one detaches the first package loaded? For instance,
> library(sqldf)
Loading required package: RSQLite
Loading required package: DBI
Loading required package: gsubfn
Loading required package: proto
but

sqldf + Date class. Ordering and summary statistics appear to be incorrect.
I've been using sqldf heavily lately but have encountered problems
with ordering of observations or calculating statistics such as max()
and min() when the variable used is of class Date.
For example, if I run the following code:

Ways to work with R and Postgres

sqldf for Very Large Tab Delimited Files
Hi All,
I have a very (very) large tab-delimited text file without headers. There
are only 8 columns and millions of rows. I want to make numerous pieces of
this file by sub-setting it for individual stations. Station is given as in
the first column. I am trying to learn and use sqldf package for this but am

How to Read a Large CSV into a Database with R
Hi, I'm working in R 2.11.1 x64 on Windows x86_64-pc-mingw32. I'm trying to

working with databases in R, so I apologize if I'm overlooking something
obvious here.
I'm trying to work with the American Community Survey data, which is two

Decimals in R/SQL
Hello,
When I am writing in sqldf or RSQLite I lose the decimals in my matrix.
The only way I can get decimals is by multiplying by 1.00000, etc. I
have tried manipulating the options, but it is only effective once I
multiply by 1.0000.
I appreciate any suggestions!
Thanks!
Example:
z <- sqldf ("select ST,
SUM(AGEP*PWGTP)*1.000000000/SUM(PWGTP)*1.00000000000000 as wgtage from

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

New package RSQLite.extfuns and minor upgrade for RSQLite
RSQLite.extfuns provides SQLite extension functions for use with
RSQLite. The package is a wrapper of extension functions written by
Liam Healy and made available through the SQLite website
(http://www.sqlite.org/contrib).
You can make the extension functions available on a per db connection
basis like this:
library("RSQLite.extfuns")
db <- dbConnect(SQLite(), dbname =
