Hi R-users I recently downloaded RdbiPgSQL 1.8.0 and Rdbi 1.8.0 from Bioconductor to be installed under R 2.4.1. When requiring RdbiPgSQL an error message is showed as follows: > require(RdbiPgSQL) Loading required package: RdbiPgSQL Error in library(package, lib.loc = lib.loc, character.only = TRUE, logical = TRUE, : ‘RdbiPgSQL’ is not a valid package – installed <

Dear R-helpers, I'm an absolute beginner using both R and PostgreSQL, but now I have to work with both programs. I need to connect R and my Postgres-database, but every attempt so far has failed (I tried using the RpgSQL package as well as RdbiPgSQL, the first, following this manual (http://code.google.com/p/rpostgresql/) didn't find any drivers for the database (step no. 1) whereas the

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

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

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

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

I have a simple vector, called tmp that I want to subset based on another vector called vec. Everything works as expected except for below where the subsetting returns something other than the original data. Any ideas? > vec <- c(1,2,3,4,5,59,60,27,32,21) > tmp [1] 1.0 1.1 2.0 2.1 2.2 3.0 3.1 4.0 5.0 5.1 6.0 7.0 8.0 8.1 9.0 [16] 9.1 9.2 10.0 10.1 11.0 12.0 13.0 14.0

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, ...)

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

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, I wish to create some 3d scatter diagrams visualising different grouped data set by a given field in the database. I tried the scatterplot3d package, as well as the plot3d and scatter3d functions (both within the rgl resp. Rcmdr package). My first question is, whether is it possibe to group data in the scatterplot3d and plot3d, because I did not succeed to use the groups = ...

To get the Rdbi/RdbiPgSQL 1.0.1 interface from BioConductor functional, I would like to suggest some fixes. Find patches and the updated packages here: http://mpa.itc.it/markus/tmp/rdbi/ Changes Rdbi: - fixed load of RdbiPgSQL (wrong name) - fixed dbConnectionInfo() (typo) RdbiPgSQL: - fixed table export to PostgreSQL - added make.names() to polish column names for R usage

Dear All, As some of you in the archive, i am experiencing problems in using RODBC with IODBC on Mac OS X Panther. I am currrently facing two problems. The first one is apparently linked with IODBC (according to returned R error message) although testing the database access from IODBC manager seems to work fine. The second is by far more radical, R purely and simply reports an error ,

Good day, I read some data from a PostgreSQL database by a following script: library(Rdbi) library(RdbiPgSQL) # conn becomes an object which contains the DB connection: conn <- dbConnect(PgSQL(), host="localhost", dbname="BVS", user="postgres", password = "*******") query_duj_kal <- dbSendQuery(conn, "select zdroj as well, cas as date, fe2,

Hi, I'm running Debian (Sid), Postgres (7.3.4) and R (1.8.1). I get the following error when I tri to use DBI >library("DBI") > p <- dbDriver("PostgreSQL") Error in do.call(as.character(drvName), list(...)) : couldn't find function "PostgreSQL" Is there any other package I need in order to interface between R and Postgres ?

I usually work with R on a windows querying data through RODBC from a postgresql db on a freebsd machine on my offcie lan. Now I have the chance to use R also on a linux gentoo client box and to connect to the same db. I know that I can install the unixodbc stuff and stick to RODBC, BUT my question is: Is there any more 'linuxish' way of querying a postgresql server from a client?

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, I post this message to the general r-help list hoping anyone within a wider range have suggestions: There are three ways to integration R and postgres, especially on 64bit Microsoft windows Platform, 1. via RODBC package, which has 32 bit and 64 bit version for windows 2. via RPostgres interface, which only has 32bit version currently 3. via plr for Greenplum, which only supports a

hi, I have been attempting to run this script and am getting some strange results. The script connects to a database and retrieves a series of tables, using sequential sql statements. I have tested all of the sql statements in the PostGreSQL terminal and they all return the desired results. I place each table into a list and run a FOR loop for 'i' in the list. The script generates
