R help - May 2011 - problem with mediation

Hello!

I have problem with mediation analysis. I can do it with function
mediate, when I have one mediator. But how I can do it if I have one
independent variable and one dependent variable but 4 mediators? I
have try function mediations, but it dosen't work. If I use mediate 4  
times, each for every mediator, is it same? I want to know what is  
total mediate effect for 4 mediators.

Hi:

Try this:

library(sos)     # install first if you don't have it already
findFn('mediation')

You should find at least a half dozen packages from which to choose,
at least three of which appear to be devoted to mediation analysis.

HTH,
Dennis
