Take a look at the results of str(Beta) List of 5 $ value : num 0.99 $ abs.error : num 4.22e-06 $ subdivisions: int 4 $ message : chr "OK" $ call : language integrate(f = dnorm, lower = -Inf, upper = 2.3552, mean = 0, sd = 1) - attr(*, "class")= chr "integrate" So it would appear that you could do Beta <-integrate(dnorm,mean=0,sd=1,-Inf,2.3552)$value Hope this is helpful, Dan Daniel J.
