Hi,
I'm trying to analyse some data I have imported into R from a .csv file but
when I carry out the aov command the results show only one degree of freedom
when there should be 14. Does anyone know why? I'd really appreciate some
help, the data is pasted below.
/The imported table looks ike this this:/
Order Transect Sample Abundance
1 Coleoptera 1 1 13
2 Coleoptera 1 2 12
3 Coleoptera 1 3 11
4 Coleoptera 1 4 13
5 Coleoptera 1 5 6
6 Coleoptera 2 1 18
7 Coleoptera 2 2 18
8 Coleoptera 2 3 16
9 Coleoptera 2 4 21
10 Coleoptera 2 5 11
11 Coleoptera 3 1 19
12 Coleoptera 3 2 16
13 Coleoptera 3 3 9
14 Coleoptera 3 4 32
15 Coleoptera 3 5 29
/The command I am using is this:/
anova2<-aov(Abundance~Transect,data=beetle)
/The results come out like this:/
Df Sum Sq Mean Sq F value Pr(>F)
Transect 1 250.00 250.000 7.2394 0.01852 *
Residuals 13 448.93 34.533
---
Signif. codes: 0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1
Cheers,
Sam
