total indirect effects in structural equation modeling using lavaan

My question.......I would like to calculate the total indirect effects of
all variables on the right-hand-side of the regression eqn's so that i can
work out the total effect (indirect effects + direct effect)

I know the direct effect and i can calculate the total indirect effects by
hand but i was wondering if there is a function that can calculate this?

In the current version of lavaan (0.5-11), there is no function that 
will compute all possible indirect/total effects automatically.

What you can do is to label the coefficients, and then use the ':=' 
operator to define the total/indirect effects that you are interested 
in. Next, you could use se="boot" to get a bootstrap based SE.

See the lavaan paper (http://www.jstatsoft.org/v48/i02/) section 7.4 for 
an example.
