Hi All, I'm interested in putting some unit tests into an R package I'm building. I have seen assorted things such as Runit library, svUnit library, packages with 'tests' directories, etc I grep'd "unit test" through the writing R extensions manual but didn't find anything. Are there any suggestions out there? Currently I have several (a lot?) classes/methods

Hi, Which is the best way to use unit tests as examples for documentation? I use testthat, but if there is a good way to do this, for example, only with RUnit, it'd still be good to know. Unit-tests are usually simple and concise, so they are good candidates for example code, but I don't want to copy them into documentation and maintain by hands. I tried to google how people handle this,

Hello everybody, as a young/unexperienced R package developer (only a few, mainly for personal use) i was thinking it could be very useful having a "meta" task view for all package-development related packages and/or function. Something like ... Creation - utils::package.skeleton, pkgKitten, Rcpp::Rcpp.package.skeleton Foreign languages interfaces: - Rcpp Documentation - roxygen2

Hi, I wonder what kind of interest there is on Test Driven Development (TDD) in R. Test Driven Development consists of writing the test before the function, and iteratively build the function until it passes the test. Python and Ruby (specially Ruby) have very strong test-oriented cultures. In fact, in Ruby at least the custom is to do TDD and lately Behavior-driven development (BDD). In BDD,

Hello, I'm writing a script that automates the testing of reverse dependencies of a package. I found the function testInstalledPackage in the tools package, which seems to do what I want. However, when I use it for a source package that was installed with --install-tests, I've noticed that only the actual test files (e.g. located in inst/tests) are available and run. In other words the

good day here, I'm maintaining a couple of R modules, both on r-forge. tests for these modules are written making use of unit testing, and I make use of the svUnit module, part of SciViews-R. I also make use of examples in the .Rd files. my question regards 'R CMD check pkg'. if an _example_ is not run correctly, I get clear feedback on the command line where I run 'R CMD

Hello, All: How can I obtain the location of an example data file in a package during "R CMD check"? I want to include sample raw data files in a package and have them read by a function in the package. It occurs to me to put such a file in "\inst\rawdata" and have examples find the data using something like "system.file('rawdata',

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I was wondering if anyone could point me in the right direction for reading up on writing tests in R. I'm writing some functions for inclusion into a package and would like to test them to ensure they're doing what I expect them to do. Are these approaches used for testing packages in CRAN? Cheers, Nathan - -- -

for the moment, I'm using: .onAttach <- function(libname, pkgname) { .bbg.db.conn <<- dbConnect(dbDriver("PostgreSQL"), user="blah","blah") } .onUnload <- function(libpath) { dbDisconnect(.bbg.db.conn) } which results in a hidden global variable in the global environment. I would prefer to make the assignment only in the package namespace.

I am trying to build a simple dll with Rcmd SHLIB to link into R. The results of the build are below. From my limited knowledge of building DLLs, it looks like it worked (I didn't get any errors).

It's fairly easy to link against the libraries from rwinlib: https://github.com/rwinlib/zeromq. I'll send you a pull request later this week to fix the binary

I see that plot.default uses deparse(substitute(x)) to extract the character name of an argument and put it on the vertical axis. Hence: foo <- 1:10 plot( foo ) will put the label "foo" on the vertical axis. However, for a function that takes a "..." list as an input, I can only extract the first argument name: x <- 1:10 y <- 10:20 foo <- function(...) {

Can someone help me with this simple example? sq <- function() { y <- x^2 y } myfunc <- function() { x <- 10 sq() } myfunc() executing the above in R yields: > myfunc() Error in sq() : Object "x" not found I understand that R's scoping rules cause it to look for "x" in the environment in which "sq" was defined (the global environment in

Have you noticed any problems with big dates (>=1/1/2040) in R?

Anyone know a quick way to color one bar of a histogram? I want to mark the bar in which the most recent observation falls. So, for instance: x <- rnorm(100) latest.ob <- x[100] hist(x) ## how do I mark the bucket that latest.ob falls into? Thanks, Whit

I will be taking over as maintainer of the its package from Giles Heywood. The code was originally written while he was working at Commerzbank. I have added the header below to the top of the R source file to indicate the changes in the copyrights for the code. The package was originally released under GPL2. I have no experience with copyright issues, and would appreciate it if someone who does
