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).
