Dear all,

How is it possible in R to calculate the following integral:
Integral(-Inf, Inf)[log(dnorm(mean = 3, sd = 1))]

how can I define that the density dnorm is taken on (-Inf, Inf)

Thanks a lot!

Er, if you mean integral with respect to the x argument in dnorm, then the answer is -Inf because log(dnorm(x,...)) goes quadratically to -Inf in both directions. If you meant otherwise, please tell us what you meant...
