similar to: No warning for conflicting methods?

( A similar problem is also reported by Sebastian P. Luque with library(maptools) library(trip) in the vignette as below ). I am writing a vignette which loads RMySQL and RPostgreSQL. This produces the warning: Loading required package: DBI Warning in .simpleDuplicateClass(def, prev) : A specification for class ?dbObjectId? in package ?RPostgreSQL? seems equivalent to one from package

(I think this is being caused by the new methods package in RC.) In the RC (March 24) some of my packages are generating a Note Note: Method with signature "MySQLConnection#integer" chosen for function "coerce", target signature "TSMySQLConnection#integer". "dbObjectId#integer" would also be valid This is coming from a call to dbGetQuery() in package

I'm having trouble getting RMySQL to load. I was able to build it and install it (RMySQL_0.5-11.tar.gz). I was also able to build and install mysql-5.0.37.

I get the "unable to load shared library, no such file" error, but all the files do exist, RMySQL.so and

I don't use MySQL but I have seen messages like this before. They often have replies which indicate that you need to follow the instructions more closely. I suggest you search the list for these previous posts as I'm sure there is help there, somewhere!

I am trying to follow directions at http://cran.r-project.org/doc/manuals/r-patched/R-exts.html#Suggested-packages regarding handling suggested packages with requireNamespace() rather than require(), and I have some questions. 1/ When I do requireNamespace() in a function is the loading of the namespace only effective within the function? 2/ At the link above in the manual it says "Note

I have a 64 bit machine running 64 bit windows 7 pro, 64 bit MySQL, and 64 bit R 2.11.1. I have also installed RTools for 64 bit windows for this version of R (archive name is oldWin64toolchain.zip; the install path for its contents is C:\RTools, if that matters). I can open up a commandline window and invoke any of the programs in both bin directories (both added to the system path). There are

For documentation we use a system that generates Rd files from special comments in the code. (inlinedocs). It is crucial to be able to get the defining source code for objects like methods to extract the comments from it. Here is an R session that shows how this works for several kinds of methods and (at the end of the session) how if fails for methods of "initialize" >

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".

Please help me to solve this problem and tell me if the RPostgreSQL

Puedes adelantar con saber que la función básica para regresiones lineales es lm() (de linear model) y para las variables que mencionas podrías utilizar: ajuste<-lm(razco_pr~razco_ps+razco_pc, data=tusdatos) summary(ajuste)

Hello R Power Users, There is a rather large introduction you may skip to go directly to my question about S4 classes. I am working on some toy code to help me get in through S4 classes. Doing this homework, I have some questions about S4 classes. I have carefully read available help and some additional material such as Robert Gentleman's slides and special attention to "Programming
