A filter function for Analysis of Variance
Anova returns a function of one argument with bindings for
The function, when evaluated, performs an ANOVA using
the covariate. It returns
TRUE if the p value for a difference
in means is less than
The covariate. It must have length equal to the number of
columns of the array that
The p-value for the test.
If set to
The function returned by
lm to fit a linear
model of the form
lm(x ~ cov), where
x is the set of gene expressions.
The F statistic for an overall effect is computed and if it has a
p-value less than
p the function returns
otherwise it returns
FALSE for that gene.
Anova returns a function with bindings for
p that will perform a one-way ANOVA.
The covariate can be continuous, in which case the test is for a linear effect for the covariate.
