Dear R users,

I am running R2.1 on windows XP SP2.  I have a problem that I fear I am
providing insufficient information to resolve.  But if anyone can suggest
directions to understand the problem I would be most grateful.

 

 

I import modest datasets which create a list of data frames (primary data
object) amounting to 15.9Mb  when measured internally by object.size() . The
sizes of the list components in the primary data object  are consistent with
the total, again when measured by object.size() All other objects in my work
area contribute less than 2Kb

 

After doing some analysis the primary data object would on occasions expand
to 800Mb but is (usually) cut back prior to saving the image of the work
area on exiting, or at sparse intervals during processing.

 

The situation now is that internally, as measured by object.size(),  my
working directory is less than 16Megs but image.save is creating an .Rdata
image in excess of 800Meg. Could this be consistent in some way?  If it is
not, or is unusual, how would I go about finding the extra, unwanted
information and removing it.

 

Any comment or suggestions would be appreciated
