Data	a data.frame to be analyzed
Term	a factor name (not interaction) to calculate the sum of square and do F test with least square means
By	a factor name to be used for slice

Details

It performs F test with a given slice term. It is similar to the SLICE option SAS PROC GLM.

Value

Returns sum of square and its F value and p-value. Row names are the levels of the slice term.
