Introduction
For these examples to work in a website, you need to change the location of the library they look for. By default they are set to use the library included in the R package rCharts, but the webserver usually can't access directly those libraries, since they are out of its reach. To avoid this issue, we can create an alias in the apache configuration for the website.
You need to open the apache configuration file, whch might be located at
/etc/apache2/sites-enabled/000-default
(adapt to your case)
Command to open the file for edition in a shell as root
nano /etc/apache2/sites-enabled/000-default
Portion to add to /etc/apache2/sites-enabled/000-default or equivalent for your site
Alias /rcharts_libraries/ "/usr/local/lib/R/site-library/rCharts/libraries/"
<Directory "/usr/local/lib/R/site-library/rCharts/libraries/">
Options All
AllowOverride All
Order allow,deny
Allow from all
</Directory>
Then you can save it (-+Ctrl+X+- in nano editor)
The whole configuration file for the site should look like the example below (adapt it to your case):
Example of configuration file for the website
<VirtualHost *:80>
ServerAdmin webmaster@example.com
DocumentRoot /var/www
<Directory />
Options FollowSymLinks
AllowOverride None
</Directory>
<Directory /var/www/>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
Satisfy Any
Allow from all
</Directory>
Alias /rcharts_libraries/ "/usr/local/lib/R/site-library/rCharts/libraries/"
<Directory "/usr/local/lib/R/site-library/rCharts/libraries/">
Options All
AllowOverride All
Order allow,deny
Allow from all
</Directory>
ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
<Directory "/usr/lib/cgi-bin">
AllowOverride None
Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
Order allow,deny
Allow from all
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel warn
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
Then restart the webserver (adapt to your case):
Command to restart apache2 in GNU/Linux boxes as root
At this time you can already use the javascript and css files provided in the package rCharts from your R scripts in Tiki, with the base url
