The "integrate" function, when evaluating an integrand function that is constant
(therefore not a function of the integral) cannot be valuated, and instead
throws an error. Instead, the interate function should evaluate the constant
function as a rectangular area with length (upper-lower).
For example:
integrand<-function(x){5}
integrate(f=integrand,lower=1,upper=5)
"Error in integrate(f = integrand, lower = 1, upper = 5) :
evaluation of function gave a result of wrong length"
