Re: [R] adaptIntegrate - how to pass additional parameters to the integrand
Hi, The package maintainer is aware of this feature request. In the meantime, I've used Currying, require(cubature) f <- function(x, a) cos(2*pi*x*a) # a simple test function adaptIntegrate(roxygen::Curry(f, a=0.2), lower=0, upper=2) HTH, baptiste On 4 May 2011 05:57, Ravi Varadhan wrote: > Ok, I get it. > > require(cubature) > > f <- function(x, a) cos(2*pi*x*a) # a simple test function > > # this works > a <- 0.2 > adaptIntegrate(function(x, argA=a) f(x, a=argA), lower=0, upper=2) > > # but this doesn't work > rm(a) > adaptIntegrate(function(x, argA=a) f(x, a=argA), lower=0, upper=2, a=0.2) > > Ravi. > > > From: r-help-boun...@r-project.org [r-help-boun...@r-project.org] On Behalf > Of Uwe Ligges [lig...@statistik.tu-dortmund.de] > Sent: Tuesday, May 03, 2011 7:17 AM > To: HC > Cc: r-help@r-project.org > Subject: Re: [R] adaptIntegrate - how to pass additional parameters to the > integrand > > On 03.05.2011 06:43, HC wrote: >> Hello, >> >> I am trying to use adaptIntegrate function but I need to pass on a few >> additional parameters to the integrand.

Re: [R] adaptIntegrate - how to pass additional parameters to the integrand
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.

[R] 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.
