tapply confusion
Hello
I have a huge data frame with three columns 'Roof' 'Month' and 'Temp'
i want to run analyses on the numerical Temp data by the factors Roof and
Month, separately and together.
For using more than one factor i understand i should use aggregate, but i am
struggling with the tapply for single factor analysis.
> tapply(Temp, INDEX = Roof, FUN = median)
This works
