Hello everybody, I am just trying to put together my first own CRAN-able package. I have completed the programming and my code works OK. But now when I perform R CMD check agsemisc_1.0-2.tar.gz and R gets to the step * checking examples ... I receive the following error message: > print(bwplot(Species~Sepal.Length, data=iris, panel=panel.bwstrip)) Error in rep(T, length(x)) : T used instead of TRUE which apparently complains about a use of T that occurs not in the example, but rather in the implementation of the function called by the example.
I have searched the R-devel archives for a reference to that error message and in https://stat.ethz.ch/pipermail/r-devel/2006-February/036520.html found a mention of function cleanEx() that is apparently generated by R CMD check(?) and that contains delayedAssign("T", stop("T used instead of TRUE"), assign.env = .CheckExEnv) delayedAssign("F", stop("F used instead of FALSE"), assign.env = .CheckExEnv) (BTW: A rather fascinating feature. I would not have thought this possible.) My questions: - Is my perception correct that this is meant as a check for robust programming style? (Because T might change while TRUE cannot?) - Is it correct that I should change ALL occurrences of T or F in my package code independent of their context? Or are there different kinds of contexts? - Are there any other similar checks that are performed by R CMD check? - I cannot find such a thing mentioned in Secion 1.3.1 of R-exts.pdf that describes the actions of R CMD check. The most pertinent item appears to be number 13: "The examples provided by the package's documentation are run." Would you say this is a documentation defect that I ought to report to R-bugs? Any help is appreciated.
