[R] ANOVA with many IV's

[Dennis Murphy]

Hi:

You can try something like this: assuming the factor variables of
interest and the response variable are in a data frame named df,

ivset <- c(<comma separated vector of factor names>)
myaovs <-  lapply(ivset, function(x) {
     form <- as.formula(substitute(yvar ~ foo, list(foo = as.name(x))))
     aov(form, data = df)
   } )

This should generate a list of aov objects, one per factor in ivset.
>From there, R has functions to extract pieces of output as needed.

Since no example data was presented, the above is untested, so caveat emptor.

HTH,
Dennis
