Use of deprecated {as.,is.,}real() functions in CRAN package fAsianOptions

[Prof Brian Ripley]

Functions real(), as.real() and is.real() have been 'deprecated' and
'for backwards compatibility only' for over 5 years now, but are still
used in your package (or something it calls, but I have tried to
elminate those).  They now give formal warnings in R-patched and
R-devel, and will become defunct shortly, most likely for R 3.0.0 in a
couple of months.

All that was needed was to use the 'double' versions.

Please submit an update to the package correcting this, to CRAN
following http://cran.r-project.org/web/packages/policies.html .

There may be other issues that need fixing: see the CRAN check logs at
http://cran.r-project.org/web/checks/check_results_NAME.html,
replacing NAME by the name of your package.
