Hello,

Despite my search, I didn't find a post-hoc test for an ANCOVA.

I used the functions aov() and lm() to run the ANCOVA then I tried
TukeyHSD() but it didn't work (because of the covariable is a continuous
variable?).

Furthermore, I would like to plot the adjusted values (i.e. the values of
the tested variable taking into account the covariable).

Thanks for your help!
