R-core, may I suggest that the error message returns the absolute path (or even the relative path) and not just the filename/basename, e.g. "Fatal error: unable to restore saved data in C:/Users/foo/.RData"
That's a good suggestion, but unfortunately not quite trivial: the code that prints that message has no idea what the full filename is. On Unix, R just tries to open ".Rdata" without ever expanding the name, and on Windows, the full name is stored in a place that this code can't see. So it's not impossible to fix this, but it would take some rearrangement of things. I'm busy on other things so I'm not going to volunteer to do it.
Curious: I'm not sure I get it (and I'm sure the code has the answer), but to open any file (on a file system) there must be a filename. I understand the case when you open a connection and then pass the connection to another function where the a error occur, but here it seems to know that the name is '.RData', or is that just hardwired in the error message? Are you saying that only then name is passed by the path is unknown? If R code, then the outer function can use tryCatch() to catch errors. If all this is implemented in cross platform R code, I can have a look at it. What functions are involved here? /Henrik

We are using R in our class. One student claims to be receiving the message "Fatal error: unable to restore saved data in .RData" The student is working in a Windows environment with Vista using the precompiled binary distribution (R-2.7.2). After searching the R site and reading FAQs, I suggested the student find .RData in the working directory and delete it. The student claims this did not work so I recommended starting R from a command line with the --no-restore option. Has anyone had any experience with this? Does anyone know what may be causing this? This is the first time I have encountered this. Paul Green
