I contacted two of the maintainers at r-forge and CRAN and they pointed me to the <a href="https://svn.r-project.org/R/trunk/" rel="nofollow">sources of R</a>, in particular the <a href="https://svn.r-project.org/R/trunk/src/library/tools/R/check.R" rel="nofollow"><code>check.R</code></a> script. if I understand it correctly: <ul> <li>scripts in the tests directory are called using a <code>system</code> call,</li> <li>output (stdout and stderr) go to one single file,</li> <li>there are two possible outcomes: ok or not ok,</li> <li>to answer this question we need patching the library/tools package.</li> </ul> <hr> I opened a <a href="https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=14702" rel="nofollow">change request</a> on R, my first guess is something like bit-coding the return status, bit-0 for ERROR (as it is now), bit-1 for WARNING, bit-2 for NOTE. from doSvUnit.R, I would <code>quit</code> with <code>status</code> 2 in case of failures and 4 in case of skipped tests. the patch would look like this: <pre><code>Index: src/library/tools/R/testing.R =================================================================== --- src/library/tools/R/testing.R (revision 57214) +++ src/library/tools/R/testing.R (working copy) @@ -352,10 +352,16 @@ } else cmd <- paste("LANGUAGE=C", "R_TESTS=startup.Rs", cmd) res <- system(cmd) - if (res) { + if (res%/%4 %% 2) { + message("NOTE") + } + if (res%/%2 %% 2) { + message("WARNING") + } + if (res %% 2) { file.rename(outfile, paste(outfile, "fail", sep=".")) return(1L) } savefile <- paste(outfile, "save", sep = "." ) if (file.exists(savefile)) { message(" Comparing ", sQuote(outfile), " to ", </code></pre> unpatched R sees anything different from 0 as ERROR.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
