workspace

I tried to load my R workspace and received this error: Error: bad restore file magic number (file may be corrupted) -- no data loaded In addition: Warning message: file ‘WORKSPACE_Wedding_Weekend_September’ has magic number '#gets' Use of save versions prior to 2 is deprecated I'm not particularly interested in the technical details, but mostly in how I caused it and how I can prevent it in the future. Here's some notes on the situation: I'm running R 2.15.1 on a MacBook Pro running Windows XP on a bootcamp partition. There is something obviously wrong this workspace file, since it weighs in

I am running a script, but it is taking much too long so I want to terminate the script. However it has calculated a lot of data which I would ideally not want to throw away. Is there an alternative to ctrl-C with which you save the internal function variables to the workspace? Ideally I'm looking for a Matlab keyboard shortcut like ctrl-C , but if that really can't be done maybe there is a way to do this in the script of my function. Any idea how to let my script react to ctrl-C as well, or maybe a GUI element which I can cancel and then I save the variables through my script? Some similar

While working to solve another problem I got this problem: I can remove all R objects by: rm(list = ls(all = TRUE)) Is there equivalent command that can detach installed packages during working session? > sessionInfo() R version 2.12.2 (2011-02-25) Platform: i386-pc-mingw32/i386 (32-bit) locale: [1] LC_COLLATE=English_United States.1252 [2] LC_CTYPE=English_United States.1252 [3] LC_MONETARY=English_United States.1252 [4] LC_NUMERIC=C [5] LC_TIME=English_United States.1252 attached base packages: [1] stats graphics grDevices utils datasets methods base require(ggplot2) Loading required package
