Variances and covariances are obtained by checking the "**Covariance Matrix**" button. For the Height-Weight data we have
Rweb:> var(variables)
Height Weight
Height 8.00000 51.22222
Weight 51.22222 538.48889

The variances are the diagonal elements and the covariances are the off-diagonal elements. In this case the variance of "Height" is 8 and the variance of "Weight" is 538.48889. The covariance between "Height" and "Weight" is 51.22222.
