Save creates huge files, dump doesn't
Make a reproducible example that focuses on the save/load aspect of the size problem. You may need to experiment with which variables need to be in the save file in order to trigger the behavior. Your example might have to involve sending us a link to a large file, but that size may dissuade busy experts from tackling it so paring it down by experimentation could be in your best interest. There is some expected behavior that can lead to larger files than the original in-memory data, but offhand I am unaware of any explanation for those files then using less space when re-loaded into memory than they occupy on disk.

Dear list,
I noticed an extremely odd behavior... I have a rather complex shiny
app which allows the user to store his/her state which internally
obviously triggers as call to save as follows
save(list=c("plots","gates","populations","cg",
"genelists","colorscores", "proj", "actds"),file=fname)
this was all working fine until some time ago (?!?) files created by
this command became several hundred MBs big... even thought the
cumulative size of all objects in memory after load() is in the 10s of
kB.
Changing to
dump(list=c("plots","gates","populations","cg",
"genelists","colorscores", "proj", "actds"),file=fname)
solved the problem, output was then only 10s of kB.
(Why/when) is this behavior intended?
Best wishes,
Lars
