commandArgs usage and --args invokation
Dear R experts:
I am a bit stymied by how the argument picking-off works in R batch file usage.
$ cat commandArgs.R
cat(" Command Line Arguments were ", commandArgs(), "\n");
$ /usr/bin/R CMD BATCH commandArgs.R --args 1 2 3
$ /usr/bin/R --args 1 CMD BATCH commandArgs.R
... I am now getting into interactive mode ?! I guess it really is skipping the
rest of the command line

processing all files with certain extension in a directory
Hi all,
I'm trying to process all files with a certain extension "*.ext" in a
directory like this:
> R --slave --args /my/dir < dir_plot.r
where I then I want to do something like:
myarg <- commandArgs()
inputdir <- myarg[length(myarg)]
print(inputdir)
"for file with extension "*.ext in inputdir"
do
data = process.data(file)

commandArgs()
Apologies for asking about this, but I don't quite understand how
this works after looking through the FAQ and the Help archives.
Let's say I want to pass "1000" as an argument to R. I did the
following:
>R CMD BATCH --1000 infile outfile
When I do print( commandArgs() ), I see
[1] ".../R.bin" "--restore"
[3] "--save"

do.call with Vectorial Argument
Dear All,
I am trying to use the do.call command to avoid tedious loops in R
when I need to call repetitively a function.
I am experiencing a problem when the arguments of a function are given
with a vector (I need to express then this way to be able later on to
integrate them numerically with the adapt package).
Consider the small script:
remove(list=ls())
#library(adapt)
# first a list of the

As a general rule, if you are using eval(parse(...)) you are doing it
poorly in R; cf

Why is something like this not suitable:

R's parsing of command line arguments using commandArgs()
Hi all,
I am setting up some R program files for use by our DB programmers to
enable them to utilize some R functions which will be called from within
TCL code. R has been installed on an RHEL server and R will process the
results of SQL queries against an Oracle database.
In some cases, they will generate a data file to be read in and
processed by R, in others they will simply make the

R-0.65.1 Startup
Dear R users,
I have noticed that my R startup is extremely slow. It takes almost 3
minutes from "double-click" to R prompt. I have been running R-0.64.1 till
recently and it took about 30 sec. I still have access to R-0.64.1. When I
started it up, it took about 25 sec. Can anyone tell me if this is a bug in
R or a problem with my machine?

commandArgs return value
Hello,
I plan to use a script with R CMD BATCH on different platforms Linux,
Windows and Mac OSX. I use the commandArgs(trailing = FALSE) function
to retrieve the name of the script and the arguments (example below
with output.) The online docs for "Introduction to R" (sections B.1
Invoking R from the command line and B.4 Scripting with R) and

Server hanging despite efforts to correct memory limits
My group is working with datasets between 100 Mb and 1 GB in size, using
multiple log ins. From the documentation, it appears that vsize is limited
to 2^30-1, which tends to prove too restrictive for our use. When we drop
that restriction (set vsize = NA) we end up hanging the server, which
requires a restart. Is there any way to increase the memory limits on R
while keeping our jobs from

vsize and nsize
I am running R version ??? under Redhat 5.2. It seems as though the
--nsize object has no effct on the size of the allocated Ncells as
determined using gc(). Yes, I have that much data....
That is if I envoke R with
R --vsize 100 --nsize 5000000
then type
gc()
I get
free total
Ncells 92202 200000
Vcells 12928414 13107200

maximum of nsize=20000k ??
Dear R-ers,
somehow it is not possible to increase nsize to more than
20000k. When I specify e.g.
> R --vsize=10M --nsize=21000K
the result is:
free total (Mb)
Ncells 99658 350000 6.7
Vcells 1219173 1310720 10.0
Maybe I have overlooked s.th....

commandArgs() prints warnings to STDOUT - correction
I realized that it is not commandArgs() rather R itslef that prints the
warning to the stdout (which is still not desirable of course):

Memory management
Dear all,
I don't get it:
First of all, the help doesn't say what are the memory limits of
R. Say, what's the max heap size for instance ????
Secondly, I invoke R with the following commands each time:
rgui --vsize 30M --nsize 1000K
rgui --vsize 30M --nsize 2000K
rgui --vsize 30M --nsize 3000K

R on os390
G'day R friends,
I didn't get any replies on the main list so I thought I'd try with the
experts.
I was wondering if anyone's ported R to os390. If so, are the vsize and
nsize limits the same as other platforms?
I could really annoy those SAS guys then.

increasing memory for R bg job

Is the following command used to increase the memory or any other command when a background R job is run?

Huge workspace cannot be opened
Hi everyone,
I have a problem that some people may have already encountered but i did not
find the solution yet.
As I use R to simulate several arrays of data, my workspace is now 35Mb big and
I cannot launch R with it.
An "xdr real data read error occured" and R tells me to delete .RData or
increase memory. I WON'T delete this file and changing the max-nsize to 40600k
