R help - May 2011 - adaptIntegrate - how to pass additional parameters to the integrand

Hello,

I am trying to use adaptIntegrate function but I need to pass on a few
additional parameters to the integrand. However, this function seems not to
have the flexibility of passing on such additional parameters.

Am I missing something or this is a known limitation. Is there a good
alternative to such restrictions, if there at all are?

Many thanks for your time.
HC

Looks like you are talking about the cubature package rather than about 
base R. Frr the latter question: Please ask the package maintainer 
rather than the list. Ideally send him code to implement the requested 
feature and the maintainer will probably add your code. Not all package 
maintainers read R-help.

For an ad hoc solution:

Just use

adaptIntegrate(function(x, argA=a, argB=b) f(x, argA=argA, argB=argB), 
......)

in order to set additional arguments for the function call.

Dr. Ligges,

Thanks a lot for providing syntax for passing additional parameters. It
worked for me and has solved my problem.

Many thanks for your quick help.
