as.data.frame and illegal row.names argument (bug in package:DoE.wrapper?)

Hi Martin,

Sorry about the confusion.  Yes, my eyes were playing tricks on me during
the copy-&-paste process :)  Thank you for helping so quickly with this.  I
am not part of the R core group to make changes to R, but I've studied the R
source code - and that of quite a few BioConductor packages - for many
years.  So I was just posting to help with why it was happening to focus the
root-cause for a fix, and how to find a possible work-around for it.

Thank you,
Paul

(This must be another typo i.e. "cut/n/paste forgot to modify" lapsus;  you
probably meant *.vector in the 2nd case).

I'm pretty sure Bill was not asking *why* this happens {he would easily find
out if he wanted} but reporting two (potential) bugs:

- one in R  [not reporting erronous as.data.frame() usage]
- one in DoE.wrapper

I'm going to look into the  R one, which is indeed in the
as.data.frame.vector() method, as you've noted.
