Full_Name: Bob Bownes Version: 2.9.2 OS: Solaris 10 Submission from: (NULL) (164.55.254.106) The sed lines in src/unix/Makefile confuse the grep distributed with Solaris that gets configured by ./configure. Switching from a separator of ':' to a separator of ',' fixes the problem. 76,77c76,77 < @$(SED) -e "s:@rhome:$(rhome):" -e

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, 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

Hello, I have this script which will be invoked as Rscript a.r < a.r a.r follows #!/usr/bin/Rscript --vanilla f=file("stdin") while(TRUE){ y=readLines(f,n=1,warn=TRUE) if(length(y)==0) break else print(y) } But it only reads one line from a.r How can I read line by line from standard input? Thank you Saptarshi

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()' character(0) character(0) which works as I expect: I am running Rscript with two arguments, namely (1)

Hi, I have an RData file containing a GeneSetCollection object (Bioconductor), http://www.cs.mu.oz.au/~gabraham/c2.RData. I think it uses lazy loading because packages are only loaded when I access the object (see below) in the R console. When I try the same with Rscript, it segfaults. This happens on 2.9.0 both on Linux and Mac: Rscript -e 'load("c2.RData"); c2[1]' ***

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 Accesses the $new method for a class defined in a package fails if the methods package is not loaded. I have created a test package with the following single code file: newTest <- function() { cl <- get("someClass") cl$new } someClass <- setRefClass("someClass") (This is similar to code actually used in the testthat package.) If methods is not loaded,

Hi, I have run into a strange issue with Rscript and plyr. When running the following Rscript: #!/usr/bin/Rscript library(plyr) d = ddply(data.frame(a=1:101,b=1:101), .(a,b), nrow) head(d) the script does not terminate. It prints out the results from head(d), but does not return to the shell. By changing the a and b to 1:100, the script returns. The same code running within the R shell works

Dear all, I am trying to use multiple version of R unpacked from CRAN deb files. It does work successfully, except for some packages installation, whether Rscript has been used. I have configured alternatives and switch R environments without any problem and can install most of the packages.

Dear all, finally decided to do an Ubuntu upgrade and a new clean R install from http://cran.r-project.org/bin/linux/ubuntu/. However, while trying to install a package from R-forge I encountered problems, involving error messages saying "Rscript execution error: No such file or directory" (see below). The same procedure works on Ubuntu 11.04 running R 2.12.1-1 from the Ubuntu

L.S. In this bug report https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=14493#c1 it is mentioned that after moving an R installation one should regenerate the Rscript executable. Is there an easy way to do so (after an R installation has been moved)? I have not found any information in the R installation and administration manual. Many thanks in advance for any pointer. Best wishes,

Dear all, I?m working as a data scientist in a major tech company. I have been using R for almost 20 years now and there?s one issue that?s been bugging me of late. I apologize in advance if this has been discussed before. R has traditionally been used for running short scripts or data analysis notebooks, but there?s recently been a growing interest in developing full applications in the

Those of you tracking R development will have noticed that we are moving towards using R as a scripting engine. (It is often overlooked as such.) Thus far INSTALL, REMOVE, SHLIB and massage-examples have been moved to R. Reasons: - it is platform-independent and needs no other tools installed. No need to worry about strange 'sh' variants (as on AIX and in the past on Mac OS X)

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.

summary: how to structure an R file such that it can be both 1. used as a script via, e.g., (from OS commandline) $ Rscript foo.r bar=baz 2. imported and called as a function via, e.g. (from R commandline) > source('./foo.r) > foo(bar='baz') ? I'm looking for the 'R equivalent' of how python supports this usecase. details: As discussed in the thread beginning

Thanks Tomas, I confirm the R Under development (unstable) (2018-04-26 r74651) version works for Rscript when the file name has a space, and no arguments are specified.

I have a program which reads in a very large data set, performs some analyses, and then repeats this process with another data set. As soon as the first set of analyses are complete, I remove the very large object and clean up to try and make memory available in order to run the second set of analyses. The process looks something like this: 1) read in data set 1 and perform analyses rm(list=ls())
