R help - Mar 2013 - Control variables in mediation analysis

Hi everyone,I would like to test a mediation model, that has several control
variables. More specifically, I would like to test the indirect effect with
bootstrapping. However, all the packages I have found so far (e.g. MBESS) only
allow testing a simple mediation model (One independent, one mediator, one
dependent) so that I cannot include any controls.
Can somebody help me?

Hi,

Just about anything can be bootstrapped, that's one of the things that
makes bootstrapping great! Use e.g., the boot package, and bootstrap
the product of the coefficients.

Alternatively the mediation package
(http://cran.r-project.org/web/packages/mediation/index.html) might
help, though I'm not sure if it uses bootstrap.

Best,
Ista
