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

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 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

how to run a R program with input arguments
I am a beginner in R and know only a little about it yet. I have a script
written in R language, named as "a.txt" for example. I am using a Linux
machine, at present I only know that I can type "R" in the terminal and then
copy-paste the content in "a.txt" to the R's interface to execute the
program. However, I want to know if there is any method that allows me to

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))

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

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

%dopar% parallel processing experiment

I am experimenting with multicore processing, so far with pretty
disappointing results. Here is my simple example:

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:

is there a way of identifying batch mode running?
Hello list
Is there a way of identifying from within R whether a script has been source(d) from Rgui.exe or via Rscript.exe in batch mode?
For the code I have I use the commandArgs() function to pick up command line args when running in batch mode via Rscript.exe
However I like to get the code working manually first using source("MyRCode.r")

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"})
}

passing args to R CMD BATCH in win 2000
Hello and sorry to bother.
Please help.
I searched the archives but could not find out why --args is being ignored
on Windows 2000.
I try

and 11.R has

print(x)
a=x[length(x)]

the argument is not passed to the R process.

Rscript -e does not accept newlines under Linux?
Hello,
I have found what I believe to be a bug in the Linux version of the Rscript binary.
Under Windows (official 64-bit 3.5.1 R distribution running on an up-to-date Win10), I can do the following (e.g. under powershell):
PS H:\Users\Cesko> Rscript -e 'ls()
>> ls()'

export variable from bash to R

This probably seems very easy to you guys, but I'm a beginner and would be
really glad if someone helped me with this:
I am trying to automate the execution of an R script (let's call it
"myscript.R") by passing a variable from a bash script to myscript.R.
I know I can use the command Rscript, but I don't know how to declare in
bash which variable will be
