Not using R 2.4.0 on Solaris. You cannot move .rda files backwards in time. From the rw-FAQ: 6.3 Can I load workspaces saved under Unix/GNU-Linux or Mac OS? =============================================================== Yes. All ports of R use the same format for workspaces, so they are interchangeable (for the same 2.x.? version of R, at least). My guess is that your .rda file contains data frames that 'will not index' because they have automatic row names, a feature of R >= 2.5.0. If so, you could try giving them explicit row names before saving. But a much better solution is to update both your R installations to R 2.6.2 (and the posting guide asked you to do so before posting). -- Brian D.
