[R] Using functions that contain sums

Hello,
I'm trying to perform an integration on a function that contains a sum.
Similarly I'm hoping whatever acts as a fix will be good enough to aid in
a 2nd case as well but I've already put in a work-around for that
situation.
My code example is here:
watermelon=c(0,1,2,3)
w<-function(x){
sum(sin(x-watermelon))}
integrate(function(x){w(x)},0,2)
integrate(function(x){sin(x)+sin(x-1)+sin(x-2)+sin(x-3)},0,2)
the first integral gives an error... the 2nd is what I should get for an
answer for the first. Is there a way to get this to work the way that I
desire?
Any help is appreciated.
Sincerely,
Patrick Joyce
