Dear list,

?require says :
"... |require| is designed for use inside other functions; it returns
|FALSE| and gives a warning (rather than an error as |library()| does
by default) if the package does not exist ..."

However when I run the following code I don't get any TRUE / FALSE
statements (but the warning only).

You never printed the value, so you didn't see it.  (It was returned
marked invisible, i.e. not for printing.)

maybe it would help if the man page said 'returns invisibly' instead of
'returns'.
