Getting Rolling With R

Today, I've written a little script that parses bag files into CSVs of the topics' messages.  Now I have to match them up and put them together into a combined dataset.  The way I described this situation earlier was,

"A bag file stores message traffic from recorded ROS topics. Messages arrive regularly, but at different frequencies."

As I tried to think of the best way to organize my datasets, I considered putting together a database.  I  balked when I realized I'd have to define tables, and declare columns with names and the appropriate datatypes (yuck).  I needed SQL functionality with the simplicity of a CSV file.  Lo and behold, I googled for 'r join datasets', and found this page:

"We often encounter situations where we have data in multiple files, at different frequencies and on different subsets of observations, but we would like to match them to one another as completely and systematically as possible. In R, the merge() command is a great way to match two data frames together."

Sounds like what I need!
