Deeply suspicious of what?
Of things that look like factors? (I don't know, I didn't write this.)
I believe that is a very old comment (probably by Ross)... I think that the point is that there are cases that are easily overlooked, such as the fact that a "column" of a data frame can actually be a matrix. The important thing that gets ruled out is string vectors (whether or not that is a good idea...), which is probably exactly what Marc F. has where he thinks he has a factor.
