Thanks for any explanations you can provide I'd like to understand what's going on. in the intricacies of $PATH setting and its post-modern interrelationships with bash.

(Maybe I gave up too easily, but I decided that I didn't need a Ph.D. It was getting very late, I was frustrated and I quit. I Googled and Googled - including a search here - and tried several solutions but nothing worked. (Debian apparently handles this differently than the other two distros in which I successfully installed TL from DVD). On my Debian setup, I finally gave up and installed TL 2009 from the official Debian repos because I ran into unexpected headaches correctly setting up the $PATH. However, when I checked, all the packages seemed to be there and the overall installation size was correct. When I first tried installing TL 2010 last night, everything finished so quickly that I imagined something had gone wrong (despite the "successful install" message).

Also, they were installed on the same PC (although on different partitions) TL 2009 was installed in my CentOS 5.5 setup, and TL 2010 was installed in my Debian 6 (Squeeze) Xfce setup. iso's were downloaded from a CTAN mirror in North America, their md5sum and sha256 sum were verified as correct prior to burning, and they were burned using the same CD/DVD optical drive. Did the TL gurus do something to reduce the package size and speed up the installation process?īoth TL. I'm wondering if anyone else has experienced this and could explain why there is such a marked difference. I am puzzled by the huge difference in installation times (from a DVD) between TeX Live (TL) 2010 and TL 2009: approx. The R Console app itself has the fewest quirks with system environment variables, and should accept your path exactly as it is set with an Rprofile or Renviron file.After searching the forum, it seems this question has not been asked. It should start as it is defined in your Rprofile or Renviron files. RStudio also has it's own startup sequence and may modify the end of your PATH variable. One final note, if you run R from a command line interface, environment variables may be inherited from your shell. I've come to prefer just setting up my path simply, and coding it directly. You can also use the strategy of setting an environment variable if it doesn't already exist and/or doesn't contain something you want it to. There are various ways of doing this that get and edit a PATH variable (e.g., tack on a new path at the end, or the beginning). An example would be: Sys.setenv("/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin") If you are creating an Rprofile file, the file should include the following line: Sys.setenv("")Īgain, don't include "". An example would be: PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin If you are creating an Renviron file, the file should include the following line: PATH= Name the files as you would in your home directory (. To create a PATH for a single project, set it in a file in that project's top level directory. Take note of the difference between how profile and environment files are named in your HOME directory vs. Here, an Renviron file should be ~/.Renvironand an Rprofile file ~/.Rprofile.

Most of the variables documented in this manual exist just to facilitate customization: some command or other part of Emacs examines the variable and. A variable is a name used to remember a value. You can also just use "~" to refer to HOME. Often the description of a command will say, To change this, set the variable mumble-foo. To create a PATH value for a single user, set it in a file in HOME, which you can find in your R session using Sys.getenv("HOME") or path.expand("~"). You can find out what R_HOME is in an R session using R.home(), or Sys.getenv("R_HOME") Rprofile for the name of a profile or environment file in this location. For a file in R_HOME/etc, Do not use Renviron, Rprofile. Here you can use either Renviron.site or Rprofile.site for the file name. To create a site wide value of PATH, you will want to set it in a file in R_HOME/etc. You may create a file called R_HOME/etc/Renviron.site, but do not edit R_HOME/etc/Renviron.

R_HOME/etc/Renviron is created on installation and should not be edited.

Don't think you can create a more specific version that simply updates what you've done in a more general configuration file. When a file is found it is used, so local takes precedence over global. The first location can contain configurations specific to a project, the second contains those specific to a user, and the third, site wide configuration settings. These locations are searched in the order numbered above.

Renviron files can only contain name value pairs, and are not interpreted as R code
