similar to: Can R read data from stdin?

I've patched R so that it can be used as a scripting language, i.e. you can (on Unix-like systems) write files containing R code and execute them non-interactively, e.g.: #!/usr/local/lib/R/bin/R.bin --script cat("Hello World!\n") I've updated the patches for R-1.7.0; if you're interested in the patches, e-mail me at mckay@gmr.com, and I'll send them to you. --

I've hacked R so that it can be used to write shell and/or CGI scripts, e.g. "hello world" can be written as: #!/usr/local/lib/R/bin/R.bin --script cat("Hello, World!\n"); The mods required to enable this aren't particularly major. (Adds about 70 lines of code, IIRC.) Anyone else interested in adding this to the R core? -- Neil D. McKay, Mail Code 480-106-359

Hello.. I am pretty new for R, but if I understand it correctly, when R read data by doing something like "d <- read.table("/dev/stdin")", it read entire data first then start processing.. Is there anyway I can tweak R around so that it will start processing as data comes and not load everthing on memory at once? The reason for this is because we have a case where

Hi. I have asked this question before and Aaron J. Mackey and Tony Plate gave me some great insight but I still can't figure out how to do what I am trying to accomplish. So let me ask again... What I am trying to do is to make R read data from pipe (stdin). Say I have following files on my directory my.dat apple 1 orange 2 grape 3 my.R d <- read.table(

I've updated my scripting patches to R-1.8.0. These patches allow you to write shell scripts in R (at least on *nix systems) by putting #!/path/to/R.bin --script on the first line of the script file.

Replying here, but several of the questions raised boil down to "couldn't you make the usage of GetUnderlyingObject conservatively correct?". I'll try and address that. I think this *is* the right approach, but I think it is very hard to do without effectively disabling this part of GlobalsModRef. That is, the easy ways are likely to fire very frequently IMO. The core idea is

Greetings folks! I would like to enable globalsmodref-aa in the non-LTO pass pipeline so that it gets tested more and there are fewer differences between the two. For all of my benchmarks, this is performance neutral, but I'd appreciate others benchmarking this combination to see if they see any benefits or regressions. You can demo this mode easily: -mllvm -enable-non-lto-gmr Please let me

Hi Chandler, I would like to run some benchmarks on ARM hardware and to look at impact of your patches on LTO.

Hey, thanks for benchmarking. How stable is the 2% regression? Michael ran some benchmarks with GlobalsModRef completely disabled and the only differences were in the noise. This was a complete spec2k6 run along with some others. Based on the number of benchmarks run there, I'm going to go ahead and submit these patches, but if you can clarify the impact here, we can look at potentially some

Can you say what Benchmark or give a test case so we understand the nature of the regression? As Gerolf said, that will be important to understand what is best to do.

Before the fix, the compiler may simply return 'noalias' for cases it can not really prove to be noalias, but actually correct by luck (or even wrong noalias, but does not result in miscompile). It would be useful to find out the set of missed noalias queries from GlobalModRef with your benchmark and examine if there is some improvement can be done. David On Fri, Jul 17, 2015 at 6:32

Rails 3.1.3 Hi. I''m a little confused with Devise and ActionMailer. It seems that Devise has its own way of sending mails through ActionMailer. Does it generate Mailer class when "rails g devise..." command is executed? Or do I need to do some special command in order to generate Mailer? I have certainly set up a devise User table but there is no Mailer class for it,

Based on function names and structures, this is some version of GCC :) Any way you can post the entire .ll file? Because it's globalsmodref, it's hard to debug without the other functions, since it goes over all the functions to determine address takenness, etc :) On Tue, Jul 21, 2015 at 3:23 PM, Michael Zolotukhin <mzolotukhin at apple.com> wrote: > Hi Chandler, > > We
