I'm trying to provide different parameters to the integrate function for
various probability functions. I'm using dnorm as the simplest example here.
For instance integrate(dnorm, -1.96, 1.96) produces the correct answer for a
normal distribution with mean 0 and standard deviation 1. I've tried two ways
to use mean=2.0 and standard deviation 1, but with no luck. The examples
follow.
> integrate(dnorm, -1.96, 1.96)
0.9500042 with absolute error < 1e-11
> mean = 2.0
> sd = 1.0
> integrate(dnorm, -1.96, 1.96)
0.9500042 with absolute error < 1e-11
> integrate(dnorm(mean=2.0,sd=1.0), -1.96, 1.96)
Error in .Internal(dnorm(x, mean, sd, log)) : 'x' is missing
Calls: integrate -> match.fun -> dnorm
Execution halted
How do I change the built in mean=0 and standard deviation=1 for dnorm using
integrate?
Thanks,
