[R] Error Message During ANOVA

[Sara Ciancitto]

I know this is several years later but...

I ran into the same issue and was able to solve it by verifying the spacing between variables within original text file. For example, Item1, Item2, and Item3 had a single space between them while the numbers in each item had 5 spaces between them, resulting in a mismatch between r and tm. 

Hope this helps somebody.
