In keeping with the vagueness of the posting, I can contribute my experience that installing Rmpi on a cluster is in general not trivial. You potentially have to ensure that your are using the correct combination of compiler and MPI implementation to build the packages and then ensure that the environment is correspondingly set up for the jobs you submit to the cluster. I would maintain that installing Rmpi should normally be done by the cluster administrator and the he/she should then be able to provide the users with the information about how to use it.

Re: [R] Convert list of data frames to one data frame

Re: [R] A question on Statistics
>From the posting guide: "*R-help* is intended to be comprehensible to people who want to use R to solve problems but who are not necessarily interested in or knowledgeable about programming." This says to me that R-help is for general questions about R programming, not statistics, though I grant you that the intersection is nonempty. Nevertheless, purely statistical issues should be posted elsewhere, and your query appears to be such. However, I'll just note: what does "centered at 0" mean for an asymmetric distribution?

Hi,
I'd like to report the following, which I suspect is a bug:
On my Windows 10 system using Emacs 25.3.1 I've got several R versions.
For example, I've got R-3.5.0 and R-devel installed under C:\Program
Files\R\R-3.5 and C:\Program Files\R\R-3.6, respectively.
Up until quite recently, I could start a specific version, e.g., the
64-bit version of R-3.5.0 by issuing 'M-x R-3.5-64bit'. This is now
broken and results in "Searching for program: No such file or
directory,
R-3.5-64bit".
I've got a couple of "older" ESS versions lying around and found
that it
still works is ess-20180514.721, but is broken in ess-20180522.213
(and still broken in ess-20180701.100). I checked the commit history
and suspect that the 'Simplify how R-X.Y.Z style functions are created'
change that got merged in on May 21 may have something to do with this
problem.
Kind regards,

I could further clarify if my question is not elaborate enough. And many apologies if it is very trivial - however still I am looking for 2nd opinion on my question. Answer to Jeff's pointer - yes my distribution is assumed to be centered at 0.

[ESS] Problem starting specific R version
Hi, I'd like to report the following, which I suspect is a bug: On my Windows 10 system using Emacs 25.3.1 I've got several R versions. For example, I've got R-3.5.0 and R-devel installed under C:\Program Files\R\R-3.5 and C:\Program Files\R\R-3.6, respectively. Up until quite recently, I could start a specific version, e.g., the 64-bit version of R-3.5.0 by issuing 'M-x R-3.5-64bit'. This is now broken and results in "Searching for program: No such file or directory, R-3.5-64bit". I've got a couple of "older" ESS versions lying around and found that it still works is ess-20180514.721, but is broken in ess-20180522.213 (and still broken in ess-20180701.100). I checked the commit history and suspect that the 'Simplify how R-X.Y.Z style functions are created' change that got merged in on May 21 may have something to do with this problem. Kind regards, Henric Winell __ ESS-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/ess-help
Re: [R] parallel processing in r...
dear Members, Thanks for the reply..I do have another issue; I will be highly obliged if you answer it: I tried "top" at the bash prompt, but it provides a way to measure CPU performance of the existing processes. I want to check the CPU usage of the execution of an R function. So I start R by this $ R and at the R prompt I type the function to be executed. But if I type "top" at the R prompt, it says object "top" not found. So, should I change to bash prompt after running the R function? If yes, how do I do it? If not, how to use "top" inside the R prompt? Again, I think this is an OS isuuebut I could'nt find any answer in the Internet. I am an independent researcher and I don't have personal access to experts...this mail list is the only vent I have... Very many thanks for your time and effort...

Use "top" at the bash prompt. Read about the "mc.cores" parameter to mclapply. Make a simplified example version of your analysis and post your question in the context of that example [1][2][3]. You will learn about the issues you are dealing with in the process of trimming your problem, and will have code you can share that demonstrates the issue without exposing private information. Running parallel does not necessarily improve performance because other factors like task switching overhead and Inter-process-communication (data sharing) can drag it down. Read about the real benefits and drawbacks of parallelism... there are many discussions out there out there... you might start with [4].
