time-ordered object list
As Uwe said, you can't really do that in R. S-PLUS can do that because it stores each object as a separate file on disk, thus you can get time stamp from the file. In R everything is in the global environment that can be saved to a single workspace (.RData by default). There have been some discussions quite a while ago on how time stamping objects in R can be done. You may want to search the archive. The mbvutils package has tools for organizing objects, but I don't know if it provides time stamps. Andy
From: Robert Kinley It's often useful to view objects in time order. In Splus I can do this with
objects.summary(order = "dataset.date")
which delivers this sort of thing ...
data.class storage.mode extent object.size
dataset.date
reference data.frame list 25 x 4

x data.frame list 15 x 4
