[Bugs-r-devel] codetools

[Uwe L. <li...@st...>]

Luke,

codetools are extremly useful and already revealed several bugs in the 
packages I am maintaining. Simply outstanding!

There is a little problem when one tries to maintain a package for both 
CRAN and CSAN. E.g., R2WinBUGS has been ported to S-PLUS by Insightful 
and we try to use the same package for both R and S-PLUS. Now, your 
codetools are claiming that objects and functions are missing for parts 
of the code that are only executed in S-PLUS. Therefore, it would be 
nice if the codetools could ignore parts of the code in

if(!is.R()){
   HERE
}

or

if(is.R()){
   ......
} else {
   HERE
}


I'm not even sure if it is really desirable to ignore the HERE parts. At 
least, when more R packages will be ported to S-PLUS, we will see a 
bunch of warnings in the daily check results on CRAN "just" caused by 
the reason mentioned above.

Best,
Uwe
