[R] Error in match.fun(f) : object 'x' not found

Dear R list,
I am having a little trouble understanding the R code. I want to compute
expectation of normal pdf.
I did the following:
integrate(x*dnorm(x, rate=1), -Inf, Inf)
Error in match.fun(f) : object 'x' not found
If I did this, I get,
integrate(dexp(x, rate=1), -Inf, Inf)
Error in dexp(x, rate = 1) : object 'x' not found
How should I fix this? I remember when I did it for curve(), it was fine.
curve(pexp(x, rate = 1/2), from = 0, to = 5)
What am I not getting here? Thank you so much!
