Thank you to Prof Ripley, Gabor Grothendieck, Dirk Eddelbuettel and others who emailed with suggestions and comments.
Dr Ripley's suggestion that I reinstall appears to have fixed the problem, though I confess I have upgraded only to 2.3.0 rather than the beta 2.3.1. I use Windows XP Pro, Service Pack 2.0 -- my apologies for not mentioning this. While this instance was not serious, in itself, is it a symptom of something more troubling? I worry that some feature of my usage has led to this problem. However, if it were something I did regularly, then it should recur. At that time, I will certainly have to try to correct whatever it happens to be. In the meantime, however, if anyone has any suggestions about what I might have done to create this problem I'd be pleased to hear them. I do (or rather, did) have multiple versions of R installed, and I do make extensive use of several libraries, including the Bioconductor set. My suspicion is that this would not occur if I were to remove old versions when I upgrade.

R runs its examples as part of it test suite, so this is not an error in R 2.2.1 (which is not current: see the posting guide which asked you to update *before* posting). One possibility is that you have strptime from a much earlier version of R in use somehow. I suggest you remove all versions of R from your system and reinstall one latest version (2.3.1 beta).
