Is there anyway to open .RData?

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.

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, horacio montenegro --- Muhammad Subianto <subianto at gmail.com> wrote:> 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 > >
