A new minor release RQuantLib 0.3.10
is now on CRAN and
in Debian.
RQuantLib
combines (some of) the quantitative analytics of
QuantLib with the
R statistical computing environment and language.

The discount curve building code in QuantLib has shown some
overly large numerical instabilities. We have used the same example parameters (taken from the Swap example in
QuantLib) for years; it currently fails to solve for a rate at some
term further out the curve. So I made the decistion to disable this just in the examples in order to not upset the
CRAN testing framework. The examples now use a flat curve instead.
I also updated one function to silence some new warnings from R-devel about symbols from another packages’s namespace (in this case
rgl, and it is just for surface plots, a purely cosmetic function).

Thanks to
CRANberries, there is
also a
diff to the previous release 0.3.9.
Full changelog details, examples and more details about this package are at
my RQuantLib page.
