[R] TukeyHSD no longer working with aov output?

[Richard M. Heiberger]

Now I am worried that you have a wrong analysis.
the aov function is perfectly happy using either factors or
numeric variables.  Are there really only two levels of time,
which is what one degree of freedom for time suggests?  Or are there
more than two level, but since aov() sees that as a numeric variable
it has only one df.

csv files can interfere with the interpretation of data values, but
not likely in this case.  They too will have numbers interpreted
as numeric.
