Extract an intact simList but with subset of objects

This is copies the non-object components of a simList (e.g., events, etc.) then selects only the objects listed in i using Copy(mget(i, envir(sim))) and adds them to the returned simList.

# S4 method for class 'simList,character,ANY'
x[i, j, ..., drop = TRUE]

Arguments

x

A simList

i

A character vector of objects to select.

j

Not used.

...

Not used.

drop

Not used.

Value

The [ method returns a complete simList class with all the slots copied from the original, but only the named objects in i are returned.
