24.43


now I want to know, if there are significant differents in the variables
OQ, GO, SK, RC depending on Tone. This I can do with an ANOVA , or??

But when I start aov in R I get the following message:

anova1 <- aov(Tone ~  OQtil4*OQ0*GOtil4*GO0*SKrhsJ*SK0*RCrhsJ*RC0,
data=gesamt)
Warning message:
"-" not meaningful for factors in: Ops.factor(y, z$residuals)

What's wrong with my Data?


Thanks for helping me
