It would be really nice if R warned you when packages had conflicting methods. For example (and this took me a couple of hours to track down), RMySQL and RPostgreSQL both define setMethod("print", "dbObjectId"), so that: library(RMySQL) getMethod("print", "dbObjectId") library(RPostgreSQL) getMethod("print", "dbObjectId") Obviously

hello, if i load the RSQLite package in addition to the RPostgreSQL package, i get various errors when trying to use RPostgreSQL functions. here is an example transcript showing one such error: ========================================================== R version 2.15.0 (2012-03-30) [...] > packageVersion('RPostgreSQL') [1] 0.3.2 > packageVersion('RSQLite') [1] 0.11.1

I'm having a problem with dotted lines (lty = 3) in the pdf output in documents generated with Sweave. In the displayed pdf, the dotted line does not show up and in the printed output, it is there but does not seem to respect the lwd argument, for example, it is very faint despite using lwd = 3. The dotted line is correct in a quartz window and if I save the Quartz window to a pdf and

Dear R folks, One of the fantastic new tools in R is `Sweave'. I have tested it so much that I know it works and produces fine documentation, and with (GNU) Emacs/ESS it is nice to work with, too. I started to have a look at including some Swoven (is that a strong verb?) documentation with my R package, but it seems that there is no model to copy among those packages that I have installed in

Hi, I've just started using RPostgreSQL within R to interrogate a PostgreSQL database. The problem I have is that a column containing dates shows up differently in R than in the database: here is the output direct from the psql database in Linux: db=> select pat_dob_dt from patients where pat_dob_dt like '%1980'; pat_dob_dt ------------ 04/05/1980 01/12/1980 04/05/1980

Hello list, I'm using R 2.9.2 on a WinXP system, and I installed the RPostgreSQL library using the package installer.

I'm starting to seriously use R and have tried to solve this issue using my reference books but I'm missing something simple. Running R-2.13.1 on Slackware-13.1. Trying to invoke RPostgreSQL so I can copy data from a postgres table to an R data-frame. I installed RPostgreSQL and the library() command shows it's present: Packages in library

Dear list users, The problem occurs when library(RPostgreSQL) is issued on R. This issue has previously appeared on R mailing list without any robust solution.

Hi R-team, While using R 2.12.2, I came across a problem that it doesn't have RPostgreSQL package in the list of "install packages". As my original code was written in R 2.11.1, I could use the RPostgreSQL package. I am moving to R 2.12.2 to use the newly added package "xtable" in newer version R 2.12.2. Please help me to solve this problem and tell me if the RPostgreSQL

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 all, I am stuck trying to get RPostgreSQL running on my Mac. PostgreSQL itself does work fine as it is able to connect with various other apps. Unfortunately the RPostgreSQL package is not available as a binary for MAC OS. Thus I?ve been trying to compile the source for quite some time now - unfortunately without success (or at least very limited success). First, running

A question, please about development of R packages: Are there any guidelines or best practices for deciding when and why to implement an operation in R, vs. implementing it in C? The "Writing R Extensions" recommends "working in interpreted R code . . . this is normally the best option." But we do write C-functions and access them in R - the question is, when/why is this

Hi, I recently upgraded to R 2.9.0 on linux x86. After doing so, I switched to the RPostgreSQL package for interfacing with a postgresql database. I am using postgresql 8.3.7. A query that works from the postgresql terminal is causing a segfault when executed from R. My sessionInfo, the error message, and the R code used to generate the error are listed below. I have noticed that a

Dear all, I'd like to use the package RPostgreSQL. I'm using R version 2.8.1 and I've download the last version RPostgreSQL.
