What about using lm rather than aov:
> youranalysis.lm <- lm(....)
and then:
> ssType3(youranalysis.lm)
?

I am trying to employ the ssType=3 argument to analyze a split-split
plot 3 factor ANOVA for which I have a missing cell. The help file for
summary.aov that describes the usage of ssType=3 says that an aov or
aovlist object is required. When trying to run the aov command for my
dataset, I get an error that indicates that I cannot use such a command
with a data frame with missing values.
How then do I get an aov file to calculate my type III sums of squares
if I cannot run the aov command with missing values? Any help would be
greatly appreciated.
