[R-pkg-devel] Notes from rchk on hdf5r package

Hi all,

I have been submitting a bug-fix version of a package and was alerted
to some notes that rchk brought up for it.

A link to the notes


and to the version of the code the package refers to


To be more specific:

The errors are more specific about usage of Rf_lang2 and Rf_lang1. I
am not very familiar with them and would appreciate some guidance on
how to fix.


Suspicious call (two or more unprotected arguments) to Rf_lang2 at
H5ToR_Post_REFERENCE hdf5r/src/convert.c:1140

Code: SEXP hdf5r_ns = PROTECT(eval(lang2(install("getNamespace"), mkString("
hdf5r")), R_GlobalEnv));

I assume this can be fixed by wrapping the "install" and "mkString" in
an additional PROTECT? Is this what it is complaining about?

The other:

calling allocating function Rf_eval with argument allocated using
Rf_lang3(S:set_ref.H5R,?,?) hdf5r/src/convert.c:1141


eval(lang3(install("set_ref.H5R"), result, _Robj), hdf5r_ns);

I remember cobbling these parts together off of the internet and don't
understand enough about the internals of R functions to know what is
going wrong and how to fix.

Any help anyone can offer would be appreciated.

Thank you!
