Hello
Thank you for the response. So if my call is
y=foo()
z=malloc ( by memory allocations , do you mean via R_alloc and
allocVector and malloc or just the former two)
Other statements
Then I need to protect y. And in my case I don't return to R since I
have embedded it.
Why is this the

Any allocation which is managed by R's memory manager, so that includes
the former two,
Thank you. So the reason I wouldnt need to protect y had I returned to
R, is because
had i had done something like
h<-.Call("boo",a)
where "boo" contains y=foo()
the assignment "<-" to h would have a PROTECT somewhere, i.e R's
assignment is doing the protection for me.

Oh! Yes, this is the GC at work, "root objects" and everything
referenced from them.
I think I'm understanding the need for PROTECT better.
Thank you

Dear R-experts,
I have a question on the formulas used in the gam function of the mgcv
package.
I am trying to understand the relationships between:
y~s(x1)+s(x2)+s(x3)+s(x4)
and
y~s(x1,x2,x3,x4)
Does the latter contain the former? what about the smoothers of all
interaction terms?

his is a query for suggestions on how best to setup the package for

documentation details and some last test cases.
The R CMD check and INSTALL processes work great on my computer. The

In R 2.9.1 Windows:

representation, just like:
