some notes on using R in Amazon's EC2
[ Bob posted this to r-sig-finance, it's relevant here too so I am taking the liberty of reposting it here (with an small editorial change to the 'official' R / Finance URL. -- Dirk, wearing his listmaster hat ] This is a follow up to a lecture I gave at the recent R/Finance 2009 Conference in Chicago http://www.rinfinance.com/. I have prepared some informal notes for those familar with R but not with Amazon's EC2 service about using R with EC2. Please see: http://blog.rgrossman.com/2009/05/17/running-r-on-amazons-ec2/ There is also a publically available Amazon AMI with R and several time series packages installed. The manifest is "opendatagroup/r-timeseries.manifest.xml" and the AMI instance ?ami-ea846283?. The notes contain more details. I'll be revising the notes, so I'm interested in any feedback. --Bob Robert Grossman Open Data Group & University of Illinois at Chicago blog.rgrossman.com
