R devel - Nov 2008 - R CMD check with Matlab and perl?

Hi, All: 

      How might one test Matlab and perl code during "R CMD check"? 

      I ask for two reasons:  First, the "fda" package exists in both
R
and Matlab, and it would help if we could run test examples in Matlab as 
part of "R CMD check".  I tried "R.matlab", but could not
get it to work
in that context. 

      Second, I have professional colleagues who write code in Matlab 
and perl, but have no unit or regression testing.  If I could test 
Matlab and perl from within "R CMD check" examples, I think I could
get
them to use it, because it would produce more "trustworthy software" 
[the "Prime Directive" of Chambers (2008) Software for Data Analysis 
(Springer)] AND give them documentation at the same time -- while 
simultaneously reducing the cost of producing and maintaining code to 
given specifications. 


      Thanks,
      Spencer

Can you run the tests from the command line?  If so, you should be able 
to call them from system() in a script in the tests directory,
or in an example section of an Rd file.

I do something a bit like this using make, and some "R like" directory
organization, to do "unit testing" of code for installing/checking 
databases. The tests/ and an examples/ directory I added are fairly 
straightforward. The fancier R things, like parsing examples out of Rd 
files, and checking that documented arguments correspond to code, are 
not so easy.

I think most of this fancy stuff is very specific to the R package 
context, but it would be useful to think about how much of it could be 
generalized.  Let me know if you want more detail on my test setup.
