Hello:
Is it widely known that objects not explicitly deleted from one
vignette in a package can be available to a second in "R CMD build" and
"R CMD check" but not when the second vignette is built manually, at
least under RStudio on Mac OS X 10.11.4 using R 3.3.0?
For an exa
Hi Peter, Martin, and others,
Thanks for your replies.
- The bugs apply to all systems that use GNU Readline, not just Linux
or Arch Linux.
- Readline version 6.3 changed the signal handling so that SIGWINCH is
no longer handled automatically by the library. This means it's not
currently p

Thank you Simon for the detailed reply. That explains much more of what I
was looking for from the R side.

The R language itself has features that limit how much
mulitthreading/parallel processing can be done. There are functions with
side effects, such as library(), plot(), runif(), <-, and <<- and there are
no mechanisms to isolate them.

As others said XPtr is not something in R so Rcpp mailing list would be the
right place for that aspect.
However, it you forget Rcpp and phrase it as an R question, you also get much
closer to the reason and answer. SEXP type is the internal representation of
all objects in R. I assume your que

Thanks for the replies. Regarding the answer by Dirk, I didn't feel like I
still understood the reasoning why mclapply or foreach cannot handle XPtr
objects. Instead of cluttering the SO question with comments I was getting
the impression that this was a limitation inherited with R objects (which

2. It basically means that R itself can only evaluate one R expression at
the time.
The parallel package circumvents this by starting multiple R-sessions and
dividing workload.

I would like to propose that Rf_mkString(NULL) and Rf_mkChar(NULL)
return NA rather than segfault.
Case: the mkString() and mkChar() functions are convenient to wrap
strings returned by e.g. external C libraries into an R vector.
However sometimes a library returns NULL instead of a string when th
