How do I make this faster?
I was on vacation the last week and wrote some code to run a 500-day
correlation between the Nasdaq tracking stock (QQQ) and 191 currency pairs
for 500 days. The initial run took 9 hours(!) and I'd like to make it
faster. So, I'm including my code below, in hopes that somebody will be able
to figure out how to make it faster, either through parallelisation, or by
making changes. I've

Rscript, hashbang, and arguments
Hi,
I have a bunch of R scripts which have the hash bang !/usr/bin/env Rscript
and I typically run these scripts by passing in some parameters like this:
./nameOfRScript arg1 arg2 ...
I know Rscript has the option to run in --vanilla. Where exactly do I
insert the --vanilla option? When I do something like this:
./nameOfRScript --vanilla arg1 arg2 ...
And I try to access the commandArgs,

How to convert a string passed as an argument to a vector?
Hi,
$ cat commandArgs.R
args=commandArgs(trailingOnly=TRUE)
args[1]+10
I have the above code. But the following command line gives me an error. I
am wondering what is the correct way to convert a string to a vector?
$ Rscript commandArgs.R 1:3
> args=commandArgs(trailingOnly=TRUE)
> args[1]+10
Error in args[1] + 10 : non-numeric argument to binary operator
Execution halted

exec subdirectory of a package
Hello,
WRE contains the following information about the "exec" subdirectory of
a package :
"Subdirectory exec could contain additional executables the package
needs, typically scripts for interpreters such as the shell, Perl, or
Tcl. This mechanism is currently used only by a very few packages, and
still experimental."
I think it would be useful to expand "very

%dopar% parallel processing experiment
dear R experts---
I am experimenting with multicore processing, so far with pretty
disappointing results. Here is my simple example:
A <- 100000
randvalues <- abs(rnorm(A))
minfn <- function( x, i ) { log(abs(x))+x^3+i/A+randvalues[i] } ?## an
arbitrary function
ARGV <- commandArgs(trailingOnly=TRUE)
if (ARGV[1] == "do-onecore") {

Can R scripts executed in batch mode take a commandline argument?
I have examined the documentation for batch mode use of R:
R CMD BATCH [options] infile [outfile]
The documentation for this seems rather spartan.
Running "R CMD BATCH --help" gives me info on only two options: one for
getting help and the other to get the version. I see, further on, that
there are options for retoring and saving sessions (which I do not need to
do in this case),

Is it possible to detect whether running as Rscript?
I would like to write a block of code that runs when a script is being
run from Rscript, but not to run if the same file is being source()d,
or submitted via ESS, etc. As a gloss I would like to write a file
that looks somewhat like:
#!/usr/bin/env Rscript
my.func <- function(...) {
#do something...
}
if ( #is.running.Rscript# ) {
do.call(my.func, commandArgs(trailingOnly=TRUE))

Command line option to an R script running through Rscript
Hi,
I know that I can use the following script to get the command line
options for an R script. But the output shows two many irrelevant
arguments. For example, I only want to pass "a", "b" and "c" to the
script. The first 5 elements in the variable 'args' are not what I
want. I am wondering what is the correct way to pass command line
options to an R script.

R scripts and parameters
A couple of weeks ago I asked how it is possible to run an R script (not a function) passing some parameters.
Someone suggested the function "commandArgs()".
I read the on-line help and found no clarifying example. Therefore I do not know how to use it appropriately.
I noticed this function returns the pathname of the R executable which is not what I need.
I meant to ask if it is

passing a variable at the command line
Dear R People:
I have used
./R --no-save -q -f e.in >stuff.out
with great success on SUSE10.1 with R-2.7.1.
My question is, please: is there a way to pass in a variable to the
e.in file? I'm fairly sure that the answer is no, but thought I'd
double check.
Thanks in advance,
Sincerely,
Erin

Is a .R script file name available inside the script?
Hi,
if we have a file called Rscript.R that contains the following, for example:
x <- 1:100
outfile = "Rscript.Rout"
sink(outfile)
print(x)
and then we run
>> source("Rscript.R")
we get an output file called Rscript.Rout - great!
Is there an internal variable, something like .Platform, that holds
the script name when it is being executed? I would like to use

combining data from multiple read.delim() invocations.
Is there a better way to do the following? I have data in a number of tab
delimited files. I am using read.delim() to read them, in a loop. I am
invoking my code on Linux Fedora 20, from the BASH command line, using
Rscript. The code I'm using looks like:

Running Shell Script with R
I'm having some trouble getting my shell script to work. I've checked out the
Intro to R Manual and a host of other websites, but I still can't get the
script to work when I submit the job to the cluster.
Here is my main R code:

Bucle for que se salte los errores
He encontrado la respuesta. EL ejemplo que puse era trivial, ya que es obvio que if(i ==0) entonces next, pero me referia a sin saber si va a ser error el modelo o no.
Para esto he encontrado la solución
for(i in -3:3){
tryCatch({
z<-1/i
> z<-z*z
> modelo<-lm(z~1)
}, error=function(e){print("es un error"})
}
Gracias de todas maneras!!!!!

plots from batchfile on windows
Hi,
On windows I'd like to run a batchfile that leaves me a plot. As a
test I have the scriptfile "test.r" which only contains:
x <- 1:10;
y <- sample( 10 )
plot( x, y )
Now I tried the following (but nothing worked):
a) "R --vanilla < test.r" in the cmd window, => that doesn't give me a plot
b) the same, but I added

one way to write scripts in R
Dear R users,
A colleague of mine asked me how to write a script (an executable text file
containing R code) in R. After I showed
him, he said that after extensive searching of the R archives, he had not
found anything like these techniques.
He suggested that I share these methods to enable others to leverage R as a
better alternative to bash/perl scripts.
So in the interest of giving back to
