Hi Peter-<div><br></div><div>Mediation 4.0 is coming out soon, with lots of new features, including the ability for treatment/pre-treatment interactions and the appropriate calculation of the ACME for different values of the pre-treatment covariate.</div>

Hi Peter,<br>
<br>
I think that the moderated mediation is being coded up right now. I'm ccing my collaborators who are taking the lead in the software development so that they can tell you when that functionality will be made available.<br>

I am looking for an R package that could handle moderated mediation (Preacher & Hayes, 2008; Edwards and Lambert, 2007), and the closest that I came across to is your package, Mediation. I went through the documentation but wasn't sure if the package could handle moderated mediation. Could you tell me whether this package is suitable to test different models of moderated mediation as outlined by Preacher & Hayes? I am a novice at R so any insight would be appreciated!<br>
