For 'VEC' you may not need to do anything -- in
a lot of circumstances it will just work.
For 'VECH' you can write a function using the
'lower.tri' function.
But it seems to me that the assumption behind your
question is that a simple function that someone else
has written is going to be better than a simple function
that you write. Not true (barring bugs).
R is egalitarian -- your functions have the same standing
as "official" functions. A lot of times it is faster to write
a function of your own rather than search out someone
else's even if you know such functions exist.

Can anyone please tell whether there is any R function to act as "VEC" and
"VECH" operator on Matrix? Yes of course, I can write a
user-defined-function for that or else, I can put dim(mat) <- NULL. However
I am looking for some R function.
Your help will be highly appreciated.
