Dear R users, I have a rather knotty analysis problem and I was hoping that someone on this list would be able to help. I was advised to try this list by a colleague who uses R but it is a statistical inquiry not about how to use R. In brief I have a 3x2 anova, 2 tasks under 3 conditions, within subjects. I also took a variety of personality measures that might influence the results under the different conditions. I had thought that an ancova would be the best test, but it might be the case that this would not work with a within subjects design. I have not found anything that explicitly states whether or not it would, but all the examples I have read are between subjects design. I also thought of investigating a manova, but it is not really the case that I have more than one DV, it is the same DV in 6 different combinations of task and condition. There were 4 personality measures and I wanted to look at the degree to which they affected the task/ condition interaction. I have explained this briefly here, but I can of course provied more details to anyone who can advise me further with this. Thanks, Mary-Jane Anderson Information Analyst Platform Project Information Services Division, NHS National Services Scotland, Gyle Square, 1 South Gyle Crescent, Edinburgh, EH12 9EB. 0131 275 7163.
