One way to do it is to add instances of these classes to a list and
save the list using putShallow at some checkpoint.  The advantage of
that is that it loads easily into R as a table.  The disadvantage is
that you can potentially end-up with a large data structure in memory
before you save it (in Swarm).

Another way to do it is to save the single instances one at a time
with different names.  An advantage of that is that saving is fast
(random access), and there isn't a growing memory cost.  However, a
complication is that you need to write some R code to iterate over key
names (e.g. data1, data2, data3) and collect them into a vector for
analysis.
