See if the following helps you understand what you want.
This won't work:
get("m.1$medoids")
But you can do
get("m.1")$medoids
lst1 <- list(a = 10, b = 20, c = 30) ##create a list
get("lst1") ## gets whole objec
get("lst1$a") ## does not work
get("lst1")$a ## works
get(paste("lst", 1, sep = ""))$a ## same as above with paste
As for alternatives, it could be suggested that you store all your mi's
in a list themselves, and then just use the lapply function to do
whatever processing you want. You then would not have to mess with
'get', 'paste', and for loops.
Best,
