List, Would someone be so kind as to point me to a function that will calculate simultaneous confidence intervals of regression coefficients based upon their distribution as (under the assumption of normal errors, with \mathbf{X} as the design matrix): $\hat{\mathbf{\beta}} \sim N(\mathbf{\beta}, \sigma^2(\mathbf{X}^T\mathbf{X})^{-1})$. 'confint' calculates individual coefficients so far as I can tell, but I need simultaneous CIs based on the confidence ellipse/ F distribution. Inverting the ellipse gives this...

...for axis labels etc. In order ensure consistency between text and graphics of some paper, I would like to include the calligraphic H (obtained in LaTeX via \mathcal{H}) in several diagrams. Is there any way to do so? Is it in general possible to use further mathematical fonts like \mathbb and \mathbf in R?
