Hello,
Before I get into troubles I ask here:
I make a call to a C function using .C. What I would like to know is if
the arguments in the .C call can also be 'temporary' objects.
An example will illustrate this:
# here we don't have a temporary
Obj1 = 5
.C("Func", as.integer(Obj1 ), ...) # certainly works
# here we do have a temporary
Obj2 = 5
.C("Func", as.integer(Obj2 + 100), ...) # is this guaranteed to work?
Is the second call valid?
Is it also valid if DUP = FALSE, or only if DUP = TRUE ?
Thanks,
Thomas
