[R] Possible bug

[konrad]

Dear all,


I recently conducted aov calculations of datasets::CO2.


When I'm using the following code: 
'summary(aov(CO2$uptake~CO2$Treatment*CO2$Plant))'. Everything is fine. 
I get a result for Plant and Treatment.


However, if using: 'summary(aov(CO2$uptake~CO2$Plant*CO2$Treatment))' 
'Treatment' is ignored.

I'm using R 3.6 on Linux Mint. Any idea why this happens?


Regards,


Konrad
