[R] Suddenly "Subscript out of bounds"

[roderick.castillo at metanomics.de]

Hello

Using R Version 2.3.1 I have setup a cronjob to update packages,
which worked successfully almost a year (it was called daily).
Basically, it runs like this:

Sys.getenv("http_proxy")
update.packages(ask=F,repos="http://cran.r-project.org")

(the http_proxy environment variable is set prior to the call).

All of a sudden, I started to get this error:

Error in inherits(x,  "factor") :  subscript out of bounds

I have no clue about what this means. Is "factor" a buggy package?

Clearly, that kind of things can happen when you just update things
automatically...

Any help with be appreciated!

Bye
Rick
