A minimal package to illustrate the behaviour of a package, containing a static vignette, depending on different R versions; specifically between version 3.3.3 (2017-03-06) Another Canoe and the current R-devel version (at creation date) 3.6.0 R Under development (unstable) (2018-06-06 r74855).
- built with the current R-devel version ´´R CMD build staticvignette´´ yells the following warning and sets the the dependency on R version 3.5.0, which is not the case, if an older R version than 3.5.0 is used:
> NB: this package now depends on R (>= 3.5.0)
> WARNING: Added dependency on R >= 3.5.0 because serialized objects in serialize/load version 3 cannot be read in older versions of R. File(s) containing such objects: 'staticvignettepkg/build/vignette.rds'Possible context for this behaviour give the R-devel NEWS https://cran.r-project.org/doc/manuals/r-devel/NEWS.html:
''R has new serialization format (version 3) which supports custom serialization of ALTREP framework objects. These objects can still be serialized in format 2, but less efficiently. Serialization format 3 also records the current native encoding of unflagged strings and converts them when de-serialized in R running under different native encoding. Format 3 comes with new serialization magic numbers (RDA3, RDB3, RDX3). Format 3 can be selected by version = 3 in save(), serialize() and saveRDS(), but format 2 remains the default for all serialization and saving of the workspace. Serialized data in format 3 cannot be read by versions of R prior to version 3.5.0.''
The package contains the R package helloworld files from RStudio as well as the directory ''vignettes''. This directory contains the a pdf document and the .pdf.asis, as described in ''R packages: Static PDF and HTML vignettes'', available under https://CRAN.R-project.org/package=R.rsp.
furthermore, the DESCRIPTION file contains the additional entries
- Suggests: R.rsp
- VignetteBuilder: R.rsp
The test.pdf is the document which results from the first entry in the google search "test pdf" (www.orimi.com/pdf-test.pdf).
