    Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning
or fetching from a remote repository or getting an error
like unable to access '...' Couldn't resolve host '...'.
Consider something like:

  
## ipython-notebook.conf
start on filesystem or runlevel [2345]
stop on shutdown

description "Jupyter / IPython Notebook Upstart script"

script
    export HOME="/home/phil/Notebooks"; cd $HOME
    echo $$ > /var/run/ipython_start.pid
    exec su -s /bin/sh -c 'exec "$0" "$@"' phil -- /home/phil/Enthought/Canopy_64bit/User/bin/jupyter-notebook --config='/home/phil/.jupyter/jupyter_notebook_config.py'
end script

## readSQLite.R
library(RSQLite)

filename <- "your_db_file.db"
sqlite.driver <- dbDriver("SQLite")
db <- dbConnect(sqlite.driver,
                dbname = filename)

## Some operations
dbListTables(db)
mytable <- dbReadTable(db,"your_table_name")

                Stop the working directory insanity
              
          
    There are packages for this now!

2017-08-03: Since I wrote this in 2014, the universe, specifically Kirill Müller (https://github.com/krlmlr), has provided better solutions to this problem. I now recommend that you use one of these two packages:

rprojroot: This is the main package with functions to help you express paths in a way that will "just work" when developing interactively in an RStudio Project and when you render your file.
here: A lightweight wrapper around rprojroot that anticipates the most likely scenario: you want to write paths relative to the top-level directory, defined as an RStudio project or Git repo. TRY THIS FIRST.

I love these packages so much I wrote an ode to here.
I use these packages now instead of what I describe below. I'll leave this gist up for historical interest. 😆
