Hello, It has been a while since my last R Devel build, and now I'm running into an issue I'm not sure how to isolate.

Yes it helped. Thank you. I don't really understand why, but. I had previously (following an off-list

Hi Gabriel, Thanks for your explanation, I totally understand that it is almost impossible to change the data structure of STRSXP. However, what I'm proposing is not about changing the internal representation, but rather about how we design and use the ALTREP API. I might do not state the workarounds clearly as English is not my first language. Please let me explain them again in detail.

Experimenting with altrep objects and v3 serialization, I discovered a possible bug. Calling DATAPTR on a compact_intseq object returns a pointer to the expanded integer sequence in memory. If you modify this data, the object values appear to be changed. However, if the compact_intseq object is then serialized (with version=3), only the original integer sequence info is written. For example,

Hello from Bioconductor, I'm developing a package to share R objects across clusters using boost library. The concept is similar to mmap package: https://cran.r-project.org/web/packages/mmap/index.html . However, I have a problem when I was trying to write Dataptr_method for the alternative string. Based on my understanding, the return value of the Dataptr_method function should be a vector

Consider the following IR example: define void @simple([4 x double] *%ptr, i64 %idx) { %stack = alloca [4 x double] %ptri8 = bitcast [4 x double] *%ptr to i8* %stacki8 = bitcast [4 x double] *%stack to i8* call void @llvm.memcpy.p0i8.p0i8.i32(i8 *%stacki8, i8 *%ptri8, i32 32, i32 0, i1 0) %dataptr = getelementptr inbounds [4 x double], [4 x double] *%ptr, i32 0, i64 %idx

Jiefei, Beyond the general response that Luke gave, to be a bit more specific to what you said, DATAPTR and INTEGER_GET_REGION involve ALTREP method execution (for ALTREP objects, obviously) so even they are not as simple and straightforward as they were a couple years ago. They should not (any longer) be thought of as being guaranteed to be essentially bare metal data retrieval from memory.

Hi, I just downloaded and installed last nights version of R-patched and decided that I'd set R_BATCHSAVE=--no-save in config.site, which I haven't done before. Since the comment above R_BATCHSAVE in config.site says: ## The default behavior of R if it encounters EOF in batch mode. ## Set this to one of '--save' or '--no-save' depending whether you ## want automatic

Rolf, looking at the configure script I believe you need to specify --with-tcl-config=/usr/lib/tcl8.6/tclConfig.sh and similarly --with-tk-config=<location of tkConfig.sh> HTH, Peter On Fri, Nov 17, 2017 at 8:43 PM, Rolf Turner <r.turner at auckland.ac.nz> wrote: > On 18/11/17 17:00, Erin Hodgess wrote: >> >> When I have compiled from sourced on Ubuntu, I did NOT

Hi together, a bit more than a month ago I have released the 'collapse' package for advanced and fast data transformation in R with an array of fast grouped and weighted functions and facilities for efficient grouped programming in R. As I am preparing the next update of this package I have come across the following: For grouping, 'collapse' uses the function 'GRP', and

I can work on this.

Hi, I am curious about whether there exist thread-safe functions in `Rinternals.h`. I know that R is single-threaded designed, but for the simple and straightforward functions like `DATAPTR` and `INTEGER_GET_REGION`, are these functions safe to call in a multi-thread environment?

It recently came to my attention that my R installation no longer has tcltk capability. I can't figure out why or what to do about it. I built R from source. I configured using the "--with-tcltk" flag. The build and install *seemed* to go OK, but after realising I didn't have tcltk capability I looked into config.log. There I found: > configure:39486: checking for
