A consensus seems to emerge : R would excel to exploratory work on small/middle-sized datasets, while SAS would be able to munch much larger datasets. However, I see the "size" problem as a red herring. The objects that have to stay "in core" are usually much smaller than the dataset. For example, for problems involving fixed-effects linear models, you need only some

Hi, i found tis message in the archive and have got the same problems ? John, perhaps you have found now a way install RPgSQL for windows2000, or anybody other ? many thanks for advance christian [SNIP] I wonder whether anyone has succeeded in building either the RPgSQL or the Rdbi.PGSQL and Rdbi packages for Windows. If so, would you be willing to share either the binary package(s) or

I've been putting together a package that defined generic methods for database access. The packages is called "Rdbi." It borrows as much as possible from existing database packages / proposals. I'd like to start a discussion about the proposed interface. Here's what I've come up with so far: # # Rdbi: connectionMethods.R # dbConnect <- function(dbObj, ...)

Sorry for the simple question: What is the "standard" package for interfacing with PostGreSQL (most up-to-date)? There appear to be at least three with different names: Rdbi.PgSQL RdbiPgSQL (available as part of BioConductor) RPgSQL (On the home page, no longer maintained in favor or Rdbi) The R and database developer page (http://developer.r-project.org/db/) was last updated in

Hi, I am relatively new at R, but I would like to be able to directly access my MySQL and PostgreSQL databases from R. I have been looking around CRAN and searching through Google, however I am not sure what are the best options. I have seen DBI - not sure how this works Rdbi - not sure how this works Rdbi.PgSQL - can install, but fails on trying to load RODBC - cannot

The only database access package I see on CRAN is DBI. But is there a PostgreSQL driver for it yet? (where?) There is no sign of an RPgSQL package on CRAN either. What to do?

Hello List, I would like to connect to a postgreSQL database on a remote server and I am wondering what is the best package to do that. I have just installed RpgSQL, RPostgreSQL, Rdbi and RODBC. The handiest to me is RPostgreSQL but I don't see how to connect to a remote server with it. For sure I can connect to remote server with RODBC, but since I am on a Mac OSX 10.6, I have quite

Dear R-Users, I store my data in an Postgres-table. I can connect with Rdbi.PgSQL, that is no the problem. The problem is the NA-Values. No-data-values are coded as -9999 in the table. But when I extrct them with any SELECT-statement, the -9999-values are treated as normal vectors. How can I tell R not to fetch the datasets containig -9999-values? thanks for your help stephan -- Linux: the

I saw in the R-digest a thread about RODBC. 1) I think that this package is *extremely* valuable : it fulfills a need quite important in the case of iterative (e. g. periodic) analyses. No need to periodically return to your data and re-dumping them ... 2) The current version has a serious bug if your datasets has missing numeric values. M. Lapsley, the original author, is aware of it, but has

This is an inquiry for all those who have been working on external data base applications. I sent an inquiry (below) to snews about this sort of thing a couple of years ago and eventually decided that I would wait to see what external database developments occurred and then revisit the problem. I hope that foundations are now better. Suppose for the sake of concreteness you have a large

I have been using RODBC for a while with no complaints (R 2.0.1 patched under WinXP), then I saw a link (http://grass.itc.it/statsgrass/r_and_dbms.html) showing that Rdbi claims to run a query in 5 seconds that takes RODBC 4.3 minutes. That was hard enough for me to believe that I wanted to try some tests myself, but I cannot get Rdbi to connect to my ODBC database. Here is what works for RODBC

Hi, I would like to be able to use R with a connection to a PostgreSQL database. I am using R 2.0.1 on windows XP. I have tried installing both the DBI and rDBI packages (which is better?) but in either case I run into the same problem - when i try to use either the dbDriver or dbConnect functions i'm told the function couldn't be found. Seems like the packages aren't installing

Dear list members, I wonder whether anyone has succeeded in building either the RPgSQL or the Rdbi.PGSQL and Rdbi packages for Windows. If so, would you be willing to share either the binary package(s) or instructions about how to set up the configure scripts? My preliminary efforts to get things going under Windows 2000 haven't met with much success. Thanks, John

Hi all, I tried to install the Rdbi_0.1-2.tar.gz and Rdbi.PgSQL_0.1-2 package. The Rdbi_0.1-2.tar.gz installed fine but the Rdbi.PgSQL_0.1-2 had some problems. The compilation routine tried to find a header called libpq-fe.h but did not find it in the standard locations. I searched through the computer but did not find a file called in this way either. What should I do to successuffly
