I want to write a function to take an argument as the response
variable of a linear model, e.g. to do anova's across a list of
variables, something like the following (except, of course, this
doesn't work):
function(x) { anova(lm(x ~ my.factor,data=my.data)) }
The x in lm() above is getting evaluated at the wrong level. How
can I make this work?
