Have you looked at the 'creditmetrics' package? creditrisk+ and
creditmetrics have some very similar model capabilities.
http://cran.r-project.org/web/packages/CreditMetrics/index.html
Also, I assume you're referring to the CSFB CreditRisk+ product, and the
models defined here:
http://www.csfb.com/institutional/research/assets/creditrisk.pdf
R has the function 'fft' for Fast Fourier Transform
The 'boot' package provides several saddle point distribution functions.
Several methods proposed by Panjer are available in the R package 'actuar'
Please share your results with this list as you experiment with these
various functions.
