Despite having used R on a daily basis for the past two years, Im encountering some difficulty performing an ANOVA on my data. What Im trying to do is the following: Given data such as: Day 1 Day 4 Day 8 2 7 2 3 2 8 3 4 7 6 6 8 1 3 4 I want to use ANOVA to determine if there is a significant change over the three days. In other stats packages I have used, I can just select this data and run the ANOVA function and get the F and p values. However in R, the anova function seems to only work with a fitted model, eg. Linear regression. This function seems to assume there is a relationship such as day1~ day 4 + day 8, but in my case there isnt I just want to perform an ANOVA without regression. If anyone could point me in the right direction Id greatly appreciate it, Thanks
