Wish List: base::source() + Add Execution Time Argument
R does provide the addTaskCallback / taskCallbackManager to run a callback function after every top level command. However there is not an equivalent interface that would be run _before_ each command, which would make it possible to time of top level calls and provide other execution measurements.

But by statement in the source file, I mean, for knowing during the execution how much time is taking, without having to wait till the end. 2017-12-21 13:06 GMT+01:00 I?aki ?car <i.ucar86 at gmail.com>: > 2017-12-21 12:46 GMT+01:00 Juan Telleria <jtelleriar at gmail.com>: > > Dear R Developers, > > > > Adding to source() base function a Timer which indicates the

Wish List: base::source() + Add Execution Time Argument
Is source() the right place for this? It may be, but we've had customers who would like this sort of thing done for commands entered by hand. And there are those who want a description of any "non-triivial" objects created in .GlobalEnv by each expression, ... Do they need a way to wrap each expression evaluated in envir=.GlobalEnv with a function of their choice, one that would

R Configuration Variable: Maximum Memory Allocation per R Instance
Dear R Developers, In the same way that MySQL/MariaDB's Engine InnoDB or MyISAM/Aria have the innodb_buffer_pool_size or the key_buffer_size for setting the maximum amount of RAM which can be used by a Server Instance: ?Would it be possible to create an R Configuration Variable which fixes the maximum amount of RAM memory to be used as Commit / Dynamic Memory Allocation? Thank you. Juan

Best R GUIs
Dear R Community Members, I would like to add to one article I have written the best Graphical User Interfaces the R programming language has. For the moment I know: A) Rstudio. B) R Tools for Visual Studio. C) Open Analytics Architect. Are there others worth to mention? Thank you. Kind regards, Juan Telleria [[alternative HTML version deleted]]

Debate: Shall some of Microsoft R Open Code be ported to mainstream R?
[Sent offlist accidentally] What concerns me first and foremost is that the licensure would have to be ironclad (including for commercial use like vanilla R now) as well as ensuring that R remains completely FLOSS. Anything ?added? to R has to be a no-strings-attached gift to R. Also, I would think that it would have to play nice with existing workflows (like OpenBLAS instead of MKL) unless

Debate: Shall some of Microsoft R Open Code be ported to mainstream R?
Dear R Developers, First of all, I would like to thank you Jeroen Ooms for taking the binary Window Builds from Duncan. I firmly believe that the R Community will benefit a lot from his work. However, the debate I would like to open is about if some of Microsoft R Open Code shall be ported from R Open to Mainstream R. There are some beneficts in R Open such as multithreaded performance:

OpenBLAS in everyday R?
Multi-threaded Math Libraries (Trough OpenBlas), taking into account that today's laptops have a minimum of 2-4 cores, are an important topic, and in my opinion, shall be included in R for the general interest. I think that the way to go would be to create a configuration setting in R's options(OpenBlas= TRUE|FALSE) which enables or disables OpenBlas in an easy way, which by default shall

OpenBLAS in everyday R?
I didn't do the compile; is there a way to check whether that was used? If not, I'll inquire with our sysadmin and report back. In any case, my suggestion was motivated by the fact that some parts of R use OpenMP while others do not, in the hope that the former could have their OpenBLAS omelet without breaking the OpenMP eggs, so to speak.

OpenBLAS in everyday R?
Please pardon my ignorance, but doesn't OpenBLAS still not always play nicely with multi-threaded OpenMP? (for example, don't race conditions sometimes crop up)? If so, it might be nice to have the ability to temporarily disable multi-threaded OpenMP (effectively: omp_set_num_threads(1)) for the duration of operations using OpenBLAS.

Duncan's retirement: who's taking over Rtools?
I agree with Moshe. It is important to maintain the independence of R as a programming language by itselft, even if it could benefit from Microsoft work (C++ Base Code, etc.), it is better in my opinion to keep it independent. Also, Duncan work and know-how shall be transferred to the next future R Core Developer which will be in charge of Duncan's roles. And, if appropriate, transfer the

Suggestion: Create On-Disk Dataframes
Dear R Developers, I would like to suggest the creation of a new S4 object class for On-Disk data.frames which do not fit in RAM memory, which could be called disk.data.frame() It could be based in rsqlite for example (By translating R syntax to SQL syntax for example), and the syntax and way of working of the disk.data.frame() class could be exactly the same than with data.frame objects.

OpenBLAS in everyday R?
Julia Programming Language uses also OpenBlas, and it is actively maintained with bugs being fixed as I have checked it out: http://www.openblas.net/Changelog.txt So I still see it ok to be included as an options(...) feature (by default off, just for safety), over other Blas libraries. R could not use Intel MKL for legal reasons (I think), because as long that R ships with GPL libraries,

OpenBLAS in everyday R?
Thanks Keith. We checked, and indeed libopenblas is not linked against libomp nor libgomp. We suspect this is because we used conda to install R and OpenBLAS. So I guess we should be barking up the conda tree instead? By the way, I also noticed on my home machine (Ubuntu), /usr/lib/libopenblas.so.0 is also not linked against those, for what that's worth.

R CMD check warning about compiler warning flags
However, and hope not to be off-topic, a git repository (github, gitlab, codeplex, etc., not just solely github) could constitute a tidy approach, and make things easier to R Core :) By putting the focus on version control, the line of changes made with each commit (With the possibility to reverse changes), and not verbose e-mails. Juan I strongly disagree. Are you aware that github is a
