Good Evening, I'm a graduate student working on a project looking at issues with R package submission and maintenance; specifically looking at the discovery and elimination of functional/failure package errors (i.e. does the package do what its supposed to do? is the underlying math correct?). Through prior knowledge and research I know there are protocols in place to discover and eliminate technical/fault errors (such as what's outlined on the R Project packages page) but haven't found anything on functional errors. As a result I had a few questions on the subject that I am hoping someone had answers or know where answers could be found: 1) How often are 'functional' package errors discovered and by what means are they discovered? 2) Is there any standardized process to handle packages with known functional errors as there is with technical errors (archiving if not fixed within the allotted time period). Thank you for your time. V/R, Peter Muenzfeld [[alternative HTML version deleted]]
