'Dynamic' 3D plot
Hi,
I am looking for a R package to draw 3d plot. But not in a static way like scatterplot3d or stuff like that. I would like to make rotate the plot, to zoom/unzoom etc..., actually to render the graph 'dynamic'... (for the biologist and bioinformatician, a R package which permitts to reproduce what pdb viewer does).
Does a Way exist to do something like that in R ?
Thanks,

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.

$ /usr/bin/R --args 1 CMD BATCH commandArgs.R

How identify args into R, sent from a command line.
Hi,
For example, I have several variables in php, like
var1 = 1, 2, 3, 5, 6
var2 = 3, 1, 8
var3 = 8, 10, 4, 0, 9, 1
I sent the arguments to R, with this line:
'/usr/bin/R --vanilla --slave --args '.$var1.' '.$var2.' '.$var3.' < script.r'
In my "script.r" I can read the arguments whit this line:
args=(commandArgs(TRUE))
args=as.numeric(args)

Hello and sorry to bother.
Please help.
I searched the archives but could not find out why --args is being ignored
on Windows 2000.

Rscript, hashbang, and arguments
Hi,
I have a bunch of R scripts which have the hash bang !/usr/bin/env Rscript

I know Rscript has the option to run in --vanilla. Where exactly do I
insert the --vanilla option? When I do something like this:

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

filename
Hey,
I'm generating a .jpeg file for a web application passing parameters to
R via cgi. R gets the parameters by using commandArgs, which are passed
to a variable named j and z
j<-commandArgs()[3]
z<-commandArgs()[4]
Later I want to use the characters strings of the argument which the
variables are holding for my filename, e.g.:

commandArgs: feature request
Dear R-core Team,
As Thomas Lumley pointed out in one of his e-mails one can use commandArgs()
to get a copy of the command line arguments supplied when R session was
invoked and then use grep to extract parameters of interest.
His solution works very well if the custom options are passed by names, e.g.
--my-option=value, but what if one wants to pass parameters by their
positions. Then it's

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

Rscript argument processing minor bug with -g
I think there's a minor bug in the argument-processing carried out by Rscript.
The effect is that if one passes "-g" as a flag to the script, it is erroneously
exposed to the main executable's argument processing and therefore generates a
message about not being able to comply with the request for a particular GUI.
Uppercase G is fine as are the other 25 letters in upper or

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")
