On Wednesday, October 2nd, 2013 I gave a brief talk on using Amazon’s EC2 cloud computing capabilities to the Bay Area R User Group. A summary of all the speakers talks can be found on Revolution’s blog. You can check out my slides below:
Here is the code that scrapes the conversion rate data. To add an entry to your crontab to have it run every hour you would type something like this in the Linux shell:
crontab -e 0 * * * * sudo R CMD BATCH /home/get_conv_rate.R
You can find the code that produces the graph here.
