(I'm the author/maintainer of the emdbook package.) I named the variance-matrix parameter Sigma (rather than sigma), by analogy with the mvrnorm() function in the MASS package. I could rename it (possibly breaking existing code) or add a synonymous sigma parameter, although I don't know how much the additional complexity is worth it. I could also add a NAMESPACE to the package so that one could specify emdbook::curve3d so one could run curve3d without actually loading the package ...
