I agree; but for our enlightnment, what are the side effects of
c()?

I believe that Prof. Ripley is referring to the following, from the
Details section in ?c:


"c is sometimes used for its side effect of removing attributes except
names, for example to turn an array into a vector. as.vector is a more
intuitive way to do this, but also drops names."


There are also examples in ?c of this behavior.
