similar to: Changing default browser in options()

Hi I asked about if there is any way of opening URLs from the help browser in the same window of the same dillo browser - here is the answer. Just to reiterate: dillo is for me the perfect browser for the help of R when you use ?...

Hello, I have been trying to figure this one out, but don't seem to go anywhere. I have a function like this: a = function(t) { max(0,t+1) } very simple, but if I pass a vector of n values to this function I expect n evaluations of max and instead I get only one value (the largest value of them all..). Is there anyway to do this without invoking a for loop? thanks, Jorge

Following the beginning tutorial, I typed help.start() and was given a choice of browsers. I picked chrome but got back that chrome is not found. I cannot seem to change or get rid of it now. I looked at /etc/R/Renviron but don't see anywhere to set browser (R_BROWSER = ${R_BROWSER ...etc) - nothing about chrome. I tried starting as "R_BROWSER= R" - same thing. How do I change the

Hi, I am interested in customizing the installation of R. I have gone through the ?R Installation and Administration? manual. But some of the stuff is not clear to me and I would like to get clarifications on the following points (for a Windows installation with R_HOME=C:\\R\\R-2.9.1 ) : 1. I understand that I need to create a file, .Renviron with the following path : R_HOME\\etc\\.Renviron where

Dear all, I have a question regarding the .First function. I have included help.start() and several libraries in my .First as: .First <- function() { help.start(browser = "netscape7") library(lattice) library(modreg) library(splines) library(MASS) library(maps)} The libraries maps and splines do not seem to be available when I start R, but I have found if I change the order

What is the correct way to globally configure R to default to single (or at least, << NUM_CPUS) threaded operation? Using R 3.3.1 (both in debian unstable or using the CRAN repository for xenial) with OpenBLAS (0.2.18) defaults to using one thread per available CPU, which isn't ideal for machines more than a couple of CPUs. Setting the environment (OMP_NUM_THREADS or

I've been kicking the following idea around for a while, and am now proposing to put some version into 1.7.0. I'd be interested in comments on the desirability and the design, before I start writing any code. S4 introduced a file .S.chapters which can contain a list of S chapters (equivalent to R packages) to be loaded on start-up. This was the germ of this proposal. Proposal: Extend

[RFC = Request for Comments] { Yes, the documentation for .Renviron is really not there (but the FAQ...); the rest is in ?Startup } In R's Startup (on Unix only??) {unless --no-environ is specified} ~/.Renviron (if there) is read as an 'sh' script before R is called, then R looks ((for the site-wide Rprofile and then)) for .Rprofile in the current directory and then for

Hi, Main objective: Let Rgui find my ~/.Rprofile and ~/.Renviron files, where ~ is equal to getwd("~"). I have few comments/questions: (A) On my WinXP Pro installation, the system environment variable 'HOME' is not availble to R, e.g. Sys.getenv("HOME") is empty. I believe this is default case (correct me if I'm wrong). However, if I set the "Start

I am having difficulty coming to grips with Appendix B.2 of the otherwise very useful "An Introduction to R" and the related help file for Startup. I am running RGui 1.6.0 on a Windows 2000 machine from the default installation. How the concepts discussed in B.2 and the Startup help file relate to what I see on my machine is something of a mystery. I quote from the Startup file:

I installed the latest R-package "R-2.1.1-1.rh4AS.i686.rpm" on a Red Hat Desktop 4 (RH EL4) machine. When I try to get help by the help.start() command an error message appears: ----- > help.start() Making links in per-session dir ... If '/usr/bin/mozilla' is already running, it is *not* restarted, and you must switch to its window. Otherwise, be patient ... sh:

Regarding user's home and working directories, is Rprofile just an old name of Renviron? or (can) should we have both files with different type of definitions? (talking about R.1.4.0 in linux).

Hi, I'm an experienced R user on windows, but new to linux. This may be an issue with how R (or Ubuntu) was install on my computer, but maybe not. I just installed Ubuntu 10.04, I have administrator privileges and am using R 2.11. Here goes: I'd like to change the location where R installs packages not included in the base installation (using install.packages()). Right now it is

Hello experienced R-ers, I'm converting from S-Plus Win 98SE to SuSE 8.1, R 1.62 and have run into som problems. 1) When I use help.start() netscape comes up OK and all links are accessible except "Search Engine & Keywords" : search doesn't work and the keywords from base doesn't respond either. ?command within R gets netscape running and works OK. 2) I haven't

I have a local library 'dart' that imports "httr". It has routines that access central patient data such as birth date, so it is heavily used locally but of no interest to anyone else. The httr library (and 300 others) are in a shared directory, referenced by everyone in the biostatistics group via adding this location to the .libPaths in their default .Rprofile.

Recently, I put CentOS 6.4 on one of the four PCs I keep behind a KVM switch. I like it a whole lot in most ways, but Fedora has spoiled me : I install almost every browser I can, and generally keep half a dozen or more open, mostly with several tens of tabs open. Iow, I use browsers as I used to use books, back in the Carboniferous when I had a desk in the stacks. Are there ways a

Hi, R people. I'm shy reporting this, as a bug in this area sounds very unlikely. Did I make my tests wrongly? I'm still flaky at all this. Let me dare nevertheless, who knows, just in case... Please don't kill me! :-) Not so long ago, I wrote to this list: > (For now, [the library code] works only for me when I do _not_ use `-l > MY/OWN/LIBDIR' at `R CMD INSTALL'

Hi, In Windows, I follow a method with customized library locations that has worked for me when upgrading to new R versions.? I have not been able to follow the same method in Ubuntu. I would like to have help. Let me explain. In windows, I add the following line: .libPaths(c(?C:/Rownlib?,?C:/R/R-4.5.0/library?)) ? ????in the file C:/R/R-4.5.0/etc/Rprofile.site I have my own list of packages in

hi, is there a way to make r open the help file in a separate window? i'm quite new to linux(kubuntu) and used to work with r under windows... thanks, katharina

Hi there, I am trying to distinguish between getOption() and Sys.getenv(). My understanding is that these are both used to set values for variables. getOption is set something like this: option("var" = "A"). This can be placed in an .Rprofile or at the top of script. They are called like this getOption("var"). Environmental variables are set in the .Renviron file
