Changes in version 1.0-1 (2014-11-11)
o replace internal MVCHNV FORTRAN FUNCTION with
R's sqrt(qchisq(p, n, FALSE, FALSE). This fixes a
problem where NaN was returned as reported by
David Charles Airey
Changes in version 1.0-0 (2014-07-08)
o After 14 years, we now feel safe enough to publish mvtnorm 1.0-0.
Many packages depend, import, or suggest mvtnorm, so this version
change also indicates that the package is now stable and, to a very
large extent, the API is frozen. We will of course continue to fix
bugs or other problems but new features are unlikely to go into this
package.
o use Authors@R in DESCRIPTION
o switch to standard NEWS format

o set.seed(29)
rmvnorm(10, ...)
produces the same first ten rows as
set.seed(29)

argument pre0.9_9993 for changing back to the `old' output. This
_DOES NOT_ apply to rmvt.
Changes in version 0.9-9993 (2012-10-22)

for unknown reasons. Redefining TVTL and BVTL as FUNCTIONs
fixed the problem.
