I'm not familiar with the mnormt package.
I'm guessing its documentation may answer some (if not all) of your questions.
Note that my package, bivariate, wraps the dmvnorm function, from the
f <- nbvpdf (
0, 0, #means X, Y
1, 1, #sds X, Y
plot (f, TRUE, arrows=FALSE)
plot (f, all=TRUE, arrows=FALSE)
