Hello:

I am running a simulation in which need to pull out the coefficients of a
multiply imputed object for each simulation.

The coefficientscould be called using the following command:
mi.txt.i@imp$Chain1$cont.y.obs@model$coefficients

THis gives me the coefficients for the first imputation (Chain 1). What I
would like to do, however, is pull out the coefficients for all Chains but
cannot figure out how.In other words, I want the coefficients from
Chain1-Chain500 saved in a matrix.

mi.txt.i@imp$Chain1$cont.y.obs@model$coefficients
mi.txt.i@imp$Chain2$cont.y.obs@model$coefficients
mi.txt.i@imp$Chain3$cont.y.obs@model$coefficients
...
mi.txt.i@imp$Chain500$cont.y.obs@model$coefficients

I tried using paste:

for (i in 1:500){
s=paste("Chain",i)
mi.txt.i@imp$s$cont.y.obs@model$coefficients
...}

But that did not work.  I also tried other variations of this looping with
no avail.

Thoughts on how to use a loop to call coefficients?

Thanks,
