Hi, (please Cc me) In xyplot (), type = "l" (or one that includes "l", *el*) is (generally) meaningful only when the 'x' variable is sorted. In practice, one either sorts the data frame before hand or writes a tiny panel function which sorts the supplied x and then calls the default panel.xyplot(). Trouble arises when there is a conditional variable as well as a

Stephen, I hope you don;t mind that I am ccing this to the r-sig-debian list. In the future, please consider asking there, in particular for Ubuntu. On 2 May 2007 at 15:56, Stephen B.

Belated thanks to all who replied to my initial query. In summary, three approaches have been mentioned to run R code "in production": 1) ShinyProxy, mentioned by Tobias, for deploying Shiny applications; 2) Docker-like solutions, mentioned by Gergely and I?aki; and 3) Solutions based on Rscript or littler, mentioned by Dirk. I can't speak to 1) because I don't currently use

Hello list, I'm having some difficulty getting rJava to load in littler. Even after a R CMD javareconf and a reinstall of littler, I get this: jlaing at xenon:~$ r -e "require(rJava)" Loading required package: rJava Loading required package: methods Error : .onLoad failed in loadNamespace() for 'rJava', details: call: dyn.load(file, DLLpath = DLLpath, ...) error: unable

Hi, I'm trying to write R scripts using littler (under Debian), and was originally using the shebang line: #!/usr/bin/env r However this picks up any .RData file that happens to be lying around, which I find a little disturbing, because it means that the script may not behave the same way on successive invocations. If you drop the /usr/bin/env trick then #!/usr/bin/r --vanilla seems to

I think that's my first true question (rather than answer) to R-help. As R has, for a long time, become my primary scripting and programming language, I'm prefering at times to write Rscript files instead of shell scripts, notably when R has nice ways to do some of the things. On a standard standalone platform with standard R, I would start such a script with

Hi - I'm curious if there is a way to get access to the location of the calling script within R. I found one way of accessing it from this thread, https://stat.ethz.ch/pipermail/r-devel/2008-April/048914.html, which recommends using either: parent.frame(2)$ofile Or FILE <- (function() { attr(body(sys.function()), "srcfile") })()$filename However, those suggestions only

Dear All I want to use R, Rscript und r alternately under one common configuration. The problem is that \"r\" can't find the package \"Rmpi\" and other packages whereas \"R\" has no problem to find. $ R --vanilla < mpiHelloWorld.r #!/usr/bin/env r library(Rmpi) # calls MPI_Init rk <- mpi.comm.rank(0) sz <- mpi.comm.size(0) name <-

Hi, I directed somebody to install R (2.6.1) on his OSX computer, following instructions from http://cran.r-project.org/bin/macosx. She can run R from the console. But plot(1:10) doesn't produce any output or open a window (as I am used to from linux). More importantly: Rscript is not in the path (minor problem ln -s is hopefully doable). I tried to put a hardcoded path to Rscript into the

I would like to simulate the effect of the command-line option --quiet from user-level scripts and startup code. From src/main/CommandLineArgs.c I learn that Rp->R_Quiet is set, and I see how that is used in main/main.c. I would use this from code in Rprofile.site. In other words, I want to be silent when --quiet is used (as e.g. by littler or Rscript) but not by R itself in normal

Dear R folks, I have several data sets I want to process automatically using R. I found littler [1] and thought this will do the trick. 1. Read in data file to a data frame using `scan()`. 2. Do linear regression. 3. Write the data and the coefficients back to a file. #!/usr/bin/env r if (is.null(argv) | length(argv)!=1) { cat("Usage:

What is the correct format for the shebang line and what options are allowed or necessary along with this? I find plenty of blogs and opinions, but few authoritative answers. I want an R script to run and update packages periodically, with a cron job that launches it. What is necessary to put in line one of the R program. Aside from the basic part #!/usr/bin/Rscript what else can there be, or

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

Hello: [Kindly Cc when replying] The question in a nutshell is this: Is there a more robust alternative to Ecdf ()? The details: I've used Ecdf () _a lot_ over the past few years and I have learned to live with its warnings. But I am running short on time and patience now [*] Here is a reproducible example: > library (Hmisc) > x <- read.csv ( file =

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

Hi. I would like to know how to start an embedded R session, and avoid datasets and the standard library packages to be loaded on startup. I've been looking at littler's code (so this is partly a question to Dirk Eddelbuettel...): > /* We don't require() default packages upon startup; rather, we > * set up delayedAssign's instead. see autoloads(). >

On UNIX one can use #! notation. It would be nice to be able to do something similar on Windows. This could be done by giving Rscript the capability of skipping over the first few lines. For example, there might be a --skip=n argument or perhaps Rscript would skip over any consecutive leading lines that begin with @ in the R file since that cannot be syntactically correct R but does have

Hi, people. I met a little problem for which someone might have a solution. Let's say I have an executable file (named "pp.R") with this contents: #!/usr/bin/Rscript options(echo=TRUE) a <- 1 Sys.sleep(3) a <- 2 If I execute "./pp.R" at the shell prompt, the output shows the timely progress of the script as expected. If I use "./pp.R | tee
