Re: [R] How should I organize data to compare differences in matched pairs?

Putting all the information in one row is going to be the easest for data entry and for analysis. If it's easier you can enter the task information in one data set and the questionnaire in another (with the same unique id ) and merge the data sets later if you need to. All you want is the data

[R] How should I organize data to compare differences in matched pairs?

I'm just learning how to use R right now, so I'm not sure what the most efficient way to organize these data is. I had subjects perform the same task twice with slight changes between the rounds. I want to analyze differences between the rounds. All of the subjects also answered a questionnaire.
