These are functions that help present linear model results. Largely, the represent alternatives in presentation to other R packages. For example, the `factorplot`

function offers an alternative to David Firth's `qvcalc`

package. This function calculates and presents exact variances of all simple contrasts. Both `DAintfun`

and `DAintfun2`

are alternative ways of presenting interactions between two continuous variables. `DAintfun2`

gives results in line with the suggestions in Brambor, Clark and Golder (2006).
