Better is to use stacked format. value testno 20 t1 ... t1 40 t1 25 t2 ... t2 20 t2 ... then anova(lm(value~testno, data=yourdata)) will give you anova table. However be carefull to keep testno as a factor. You could also consult some introductory literature which can be find on CRAN, especially about data manipulation and linear models. Maindonald, Verzani or Faraway is a good starting choice.
