R help - Feb 2007 - Migrating .RData from Windows to Linux?

I want to begin a migration of R workspaces from Windows to Ubuntu Linux.

(1)  Can someone suggest the most appropriate path?
      dump()  ?
      save()  ?

(2)  Are there any R platform migration related resources "out there"?
      (I have not found any yet).

Thank you,

The easiest way is to use save() (or even save.image()) then load().

All R platforms use the XDR representation of binary objects in binary
save-d files, and these are portable across all R platforms. (ASCII
saves used to be useful for moving data between platforms but are now
only of historical interest.)


Beyond that, you should review the R Installation and Administration
manual, which is available in your installation or on CRAN.  That will
cover platform specific issues.

It helps to READ THE DOCUMENTATION!!!!

 	A dump file can be sourced into another R (or perhaps S) session,
 	but the function save is designed to be used for transporting R
 	data, and will work with R objects that dump does not handle.


Using R, I work in WindowsXP, Gentoo (64bit) and RedHat (32bit) Linuxes, 
and - every so often - MAC OS X. And have worked under Solaris and Windows 
98.

I routinely port the files produced by save() on one system to another 
system.  I cannot remember ever having had a problem doing this.

Looks like the documentation was correct! ;-)
