Set the repository for R

Every time you install a R package, you are asked which repository R should use.
To set the repository and avoid having to specify this at every package install, create a file .Rprofile in your home directory with the following text:
       myrepo = getOption(“repos”)
       myrepo[“CRAN”] = “http://stat.ethz.ch/CRAN/
       options(repos = myrepo)
       rm(myrepo)
 
 

Using the Gams Manuals in Gams-Mode

You can call the help and solver files from within Gams.mode hitting C-c Enter. Be sure that the directory for the help files is properly set (choose Customize Gams mode for Emacs from the Gams menu) and search for the following entry in the buffer:
 
If you hit enter, the gams manual is shown in your PDF viewer, but you can also search for another file. For example: type path and hit tab for completion: Gams-mode will show you two completions for ‘path’: PATH-Solver and PATH-LP-Solver.
You should also set the path of the PDF file viewer (the variable gams-docs-view-programs):
 

Do not forget to save the settings, which you can do at the beginning of the settings buffer.
You can set them for the current or/and for all future settings:
 

More on project management with Org

In one of my posts I talked about org-mode and how I use remember to organize my tasks, calls, etc. For every project I have such an org-file. I now added a file projects.org with all my projects for my different jobs. Here you see my projects for Ecoplan:
 
 
The project entry in this list is linked to my org-file for that project. In Emacs you can add a link by hitting C-u C-c C-l. It asks you for the path to the file and a description. The advantage of this file is that I now have an overview of my active projects and can quickly jump back and forth to organize my day.
 
Another thing I added in my org-files for a specific project is a list with file names. Because I work on a lot of projects I usually forget after a few days the content of my files. Below you see my active files for the project P-EVE. I used Org to make a table and quickly add every new file I work on with a short description. Of course: the file name in the table is linked to the file itself.
