Thank you very much to Tony Plate for his really clear explanation, and to
Prof Ripley for his time solving this deficiency (IMHO)

Dear all
I recently noticed the following error when cohercing a
data.frame
From ?data.frame:
Details:
A data frame is a list of variables of the same length with unique
row names, given class `data.frame'.
Your example constructs an object that does not conform to the definition
of a data frame (the new column is not the same length as the old
columns).
