You haven't told us your S-PLUS version. At least on 2000 and 5.1
you can use objects.summary. That has a dataset.date field, but
I think you will need to do some work on it to extract the date
(rather than date and time to the nearest second). Sorting on that
might be interesting:
zz <- objects.summary()
zz[sort.list(zz$dataset.date), "dataset.date", drop=F]
dataset.date
lmix2a 1999.04.08 17:05
p 1999.04.08 17:06
sps 1999.08.04 16:09
tt 1999.10.04 13:59
acc.bin 1999.10.26 17:18
z 1999.11.10 11:59
junk 2000.02.18 17:07
tablename 2000.03.08 9:47
....
objects.summary exists on 3.4, but seems pretty confused about dates
past 1999, and a colleague reported yesterday that 4.5 has the same
problem (and got told it was long past the time he should have
installed his upgrade).
