similar to: R-Oracle (was Internal data types)

Hi- I'm very interested in using R, though I am still new to it. However, all of the data I'm working with is currently stored in Oracle. So, either I get data from Oracle, save it to a text file, and then import it to R, or I write an R <-> Oracle bridge. I've taken the second approach, but I'm sure that I haven't done it entirely correctly. For starters, is there

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

Great news! Having spent a significant amount of time porting/mantaining some packages on S4/Splus 5.x and R, I'm interested in your experience as you port Hmisc and Design; I'd like to know of your progress in order to help improve available R/Splus portability tools both at the C and the S language code. These tools include the package SLanguage written by John Chambers, and

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, The current lattice/grid packages seem to position character plotting symbols (e.g., ".") differently than the base function points. The following shows what I mean: ## plain old points() positions the pch="." right at y = c(0,1), ## and thus abline(h = c(0,1)) completely hides the points "." ## (provided the output device has enough resolution, like

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, Summary: I ran into some unexpected behavior in approx() and tapply() that introduced NA's in "clean" data due to (?) numerical accuracy/round off. The culprit seems to be in match() that coerces it's arguments to character, loosing precision in the process. [R development version 1.2.0, 08 Nov 2000, on Linux] Example: > r > [1] 0.6931472 0.6931472 0.6931472

Hi, We are trying to get OpenSSH-1.2.2 stable release to compile under Solaris 2.3 Sparc. It worked perfect for Solaris 2.5, Solaris 2.5.1, Solaris 7 (All on Sparc) and Linux 2.2.13 Intel x86 OpenSSL installs fine without problem, zlib is installed fine without problems and egd.pl installs fine without problems. These are all the current releases, I can get the version numbers if you need

I'm having some trouble following the instructions in the FAQ for debugging. I can run 'R -d gdb' at the command line and it works; also, I have run gdb from emacs before. But I can't figure out how to put the two together: I've tried following the instructions in the FAQ, but I seem to be missing something. Can someone with experience tell me exactly how I should invoke gdb

Hi: I am trying to create a dynamic latex table using \Sexpr{} but it's not evaluating it. I also tried the example below without Sweave and also fails. I have also copied the Sweave.sty to my working directory but nothing seems to work. Do I need to have certain package in order to run \Sexpr{}? \documentclass[a4paper]{article} \usepackage{C:/R/R-2.8.1/share/texmf/Sweave} \begin{document}

Calls of the form data(package = pkg) inside a function incorrectly fail ("pkg" is a local variable). For instance, foo <- function(pkg) data(package = pkg) foo("base") Error in .find.package(package, lib.loc, verbose = verbose) : none of the packages were found ## workaround -- force argument "package" to be an expression ## (not a

Hi, I agree that replacing data.frames for modeling functions would be too painful. Also I agree with Thomas that new class(es) for tabular data should not inherit from data.frame, and that data.frames should conceptually inherit from some other base tabular data class. At this point I'm not suggesting anything in concrete --- I haven't sorted it out in my own mind --- but I want

Hello all- I'm having some problems with memory consumption under R. I've tried increasing the appropriate memory values, but it keeps asking for more; I've even upped the heap size to 600M, significantly eating into swap (256M real, 500+M swap). So, performance slows to a crawl. What I'm trying to do is run isoMDS on a 4000x4000 matrix. My first question is, how much memory

Hi, I just had a very quick look at the StatDataML proposal --- nice work! At the risk of showing my ignorance, I want to mention my first impressions. My first impression is that defining datasets in terms of arrays and list is a bit too high a level. What about simpler vectors, scalars? (I know that R/S don't have scalars, but other systems/applications do.) Can we think of a core

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

I'd like to propose that the whenever the length of condition passed to an if or a while statement differs from one, an error is produced rather than just a warning as today: > x <- 1:2 > if (x == 1) message("x == 1") x == 1 Warning message: In if (x == 1) message("x == 1") : the condition has length > 1 and only the first element will be used There are
