Hi, I had problem during SJava and ROracle installation. I use "R CMD INSTALL -c SJava_0.65-0.tar.gz" command to install SJava pakage. After installation, I start R session and type library(SJava), error happened as: > library(SJava) Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library

Hello everybody, I found that queries (send by "dbExecStatement" ) with more than 4000 characters length produces an error in ROracle (ver 0.3-3). Maybe there is a limitation of 4kB.... Is this a bug? If yes, is this problem solved in the latest version of ROracle (ver 0.5-0)? My system information: platform sparc-sun-solaris2.8 arch sparc os solaris2.8

Hi there! Is ROracle available for Windows, please? I found a download site, but it's really for UNIX/Linux. Here is a "thought question", please: Why do the vector elements start at location 1 rather than zero, as C does? Thanks in advance! R Version 1.9.1 Windows Sincerely, Laura Holt mailto: lauraholt_983 at hotmail.com

Hi, I have a problem executing "library(ROracle)" in R: OS/Software: Redhat 8.0, all available patches applied Oracle 9i v9.2.0.1.0 R v1.7.0 ROracle v0.5-0 DBI v0.1-5 The compilation and installation of ROracle went fine.

Hello, I have installed the ROracle and DBI packages, and I want to access an Oracle database that is not on the same machine as the one I am running R on. I can access the database remotely with perl DBI and Java JDBC. Does anyone know if this is possible using R DBI/ROracle ? I have looked through the documentation and also tried to guess at things which might work, but with no success. I

Howdy, When doing a install.packages("ROracle") in R I'm getting the following error: R CMD COMPILE RS-DBI.c make[1]: Entering directory `/tmp/R.INSTALL.1809/ROracle/src' gcc -I/usr/lib/R/include -I/usr/local/include -D__NO_MATH_INLINES -mieee-fp -fPIC -O2 -m486 -fno-strength-reduce -g -c RS-DBI.c -o RS-DBI.o make[1]: Leaving directory `/tmp/R.INSTALL.1809/ROracle/src'

I am trying to use R interfaced with MySQL. Present goal is that R should calculate the 85% quantile of AvgSpeed for each LinieID. Looking through documentation of the RMySQL Package, I guessed that dbApply would do the trick due to this example ## compute quanitiles for each network agent con <- dbConnect(MySQL(), group="vitalAnalysis") res <- dbSendQuery(con,

Oracle is finally up and running on RH 7.3 now. I will try to summarize the pitfalls to avoid here for future reference. 1> Make sure you have the Pro C/C++ drivers in Oracle client installed. This can be verified by looking for the existence of the proc directory in $ORACLE_HOME. Existence of proc means it worked 2> Put the following in the .bashrc script in root export

Hi all, This is a potentially very stupid question about MySQL <-> R interaction, but I have not been able to solve it. I'm just trying to connect R to my MySQL databse, and gets this: > library(RMySQL) Loading required package: methods > m <- dbDriver("MySQL") > con <- dbConnect(m,group="testdb") Process R segmentation fault at Wed Oct 16 07:04:30

1. Is it always the case that when defining generic functions in a package, the package needs to be installed as a binary package to avoid having the generic functions in the .GlobalEnv? 2. Defining a generic function in a "non-binary" package triggers a check warning $ R CMD check ... ... * checking for code/documentation mismatches ... WARNING Objects

Hi R users and Dr. Uwe Ligges: I read on the ROracle pre-compiled binary README file that: "Although the package ROracle passes make check, it seems to be dangerous to distribute it: I do not have the software available this package depends on." Why it is dangerous to use ROracle for windows? What software does ROracle depends on in windows platform? Is there a GNU solution for an

Hi there, I tried to install ROracle package (Windows XP pro), got the following errors; *C:\Program Files\R\R-2.6.2\bin>rcmd install "c:\ROracle_0.5-9.tar.gz"* * installing to 'c:/PROGRA~1/R/R-26~1.2/library'* *---------- Making package roracle ------------* * ********************************************** WARNING: this package has a configure script It

I have a problem when using the RMySQL package and the methods package together (R version 1.5.0) I do : library(RMySQL); m<-dbManager('MySQL') con<-dbConnect(m); quickSQL(con, ' select blah blah..'); This works fine . However when I then do: library(methods); and then repeat my sql : quickSQL(con, ' select blah blah..'); I get the following error: Error in

Hi, I need to use ROracle to communicate with Oracle from R program in windows environment. I am using Oracle 10g, R 2.6.2. I found a pre-compiled binary for ROracle for Oracle version 9.2. When I am trying to use it with Oracle 10g I get the following error: con <- dbConnect(drv, "user/passwd at dbname"); Error in function (classes, fdef, mtable) : unable to find an inherited

Another naive stats question. I'm trying to better understand what boxplots are telling me. I think what I see is the median and the boundaries of the 1st and 3rd quartiles. The whiskers represent the range of the data unless there are points which are outside "range" (default: 1.5) times the distance from the median to that quartile. Is that right? I've read the

An update to the ROracle package is now in CRAN. Version 0.5-0 * This version has an experimental dynamic SQL binding to data frames. SQL statements can be "prepared" (parsed and cached for improved performance), and columns of data frames bound to them for automatic data transfer). For details see the help() for "Oracle", "dbPrepareStatement" and

Hi, In section 4.6.7 of "Writing R Extensions" (Version 1.2.1, 2001-01-15) the C function defineVar() is described as "... the equivalent of assign(symbol, value, envir = rho, inherits = FALSE) ..." I interpreted the above (wrongly) as meaning that defineVar() makes a copy of its "value" argument into the object whose name is specified in "symbol" in

Hi, I am trying to install the ROracle package in a Linux-64 machine. I downloaded from Oracle's site their Instant Client bundle but it seems that ROracle needs some stuff not included in that kit in order to compile (in particuar, the 'proc' executable). I did not find any other linux client suite in Oracle's site, (our db runs on a Solaris server, so I can not use the
