#2: Even Easier Package Registration

March 30, 2017
By

Welcome to the second post in rambling random R recommendation series, or R4 for short. Two days ago I posted the initial (actual) post. It provided context for why we need package registration entries (tl;dr: because R CMD check now tests for it, and because it The Right Thing to do, see documentation in the posts). I...

March 29, 2017
By

Welcome to the first actual post in the R4 series, following the short announcement earlier this week. Context Last month, Brian Ripley announced on r-devel that registration of routines would now be tested for by R CMD check in r-devel (which by next month will become R 3.4.0).

A new release of RcppTOML is now on CRAN. This release fixes a few parsing issues for less frequently-used inputs: vectors of boolean or date(time) types, as well as table array input.

Suggests != Depends

March 22, 2017
By

A number of packages on CRAN use Suggests: casually. They list other packages as "not required" in Suggests: -- as opposed to absolutely required via Imports: or the older Depends: -- yet do not test for their use in either examples or, more commonly, unit tests. So e.g. the unit tests are bound to fail because, well, Suggests != Depends. This has...
