Dear R-list,
I have a problem to open my R workspace.
When I try to open my file .Rdata with double-clik on windows explore I 
get the error like this:

Error in load(name, envir = .GlobalEnv) : error reading from connection

and on windows error:

Fatal error: unable to restore saved data in .RData

I try with,

 > load("CaseStudyHouseID50.RData", .GlobalEnv)
Error in load("CaseStudyHouseID50.RData", .GlobalEnv) :
         error reading from connection
 >

 > load("CaseStudyHouseID50.RData")
Error in load("CaseStudyHouseID50.RData") :
         error reading from connection
 >

I have done to save my R workspace like this:
################################################################################
   save(list = ls(all=TRUE),
        file = "CaseStudyHouseID50.RData")
################################################################################

What is wrong?
Is there anyway to open .RData?

Regards, Muhammad Subianto

Hi

Your .Rdata file is probably corrupted. Unless you have a working 
copy of it elsewhere or sources of your data together with history 
of your commands you are probably in deep trouble .Rdata is a 
binary format and it is not recommended to safe and reliable saving 
of your work as you have only limited, if any, possibilities to 
recover it if anything goes wrong.

I usually have all my important source data in txt or xls format and 
I frequently save history in separate files (on daily basis or 
sometimes several times a day) to be able to repeat everything I 
have done.

Cheers
Petr

hi

     It seems that, in some cases, saving a .RData
containing objects from some packages and later trying
to start R (or load the .RData) before loading the
package could cause this error. See

http://finzi.psych.upenn.edu/R/Rhelp02a/archive/46910.html

     If the .RData contains objects from some specific
packages, try loading the package first and then load
the .RData file.

     Also, RSiteSearch(".RData corrupted") results in
lots of hits.

     hope this helps,
