I too would like this (being an Indian!). Here is an example that came up just yesterday with regards to solving a quadrature problem using the "cubature" package. The adaptIntegrate function does not allow additional arguments via ...
Uwe suggested a work around, but `Curry' would solve it nicely (and it also tastes better!): Curry = function(FUN,...) { .orig = list(...) function(...) do.call(FUN,c(.orig, list(...))) } 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) # Use of Curry adaptIntegrate(Curry(f, a=0.2), lower=0, upper=2) Best, Ravi. ------------------------------------------------------- Ravi Varadhan, Ph.D. Assistant Professor, Division of Geriatric Medicine and Gerontology School of Medicine Johns Hopkins University Ph.

I thought I might bring this up again - it now seems like Curry would be a natural fit with Reduce, Filter, Find, Map, Negate and Position. Any chance we might see this in a future version of R?
