Create Functions List

Description

Partially applies (the standard Curry function in functional programming) a list of arguments to a function and returns a list of preapplied functions. The result of this function is a list of functions suitable for the multiple evaluation functions in permTest.

Usage

createFunctionsList(FUN, param.name, values, func.names)

Arguments

FUN	Function. the function to be partially applied
param.name	Character. The name of the parameter to pre-set.
values	A list or vector of values to preassign. A function will be created for each of the values in values. If present, the names of the list will be the names of the functions.
func.names	Character. The names of the functions created. Useful to identify the functions created. Defaults to the names of the values list or to Function1, Function2... if the values list has no names.

Value

It returns a list of functions with parameter param.value pre-set to values.

Note

It uses the code posted by "hadley" at http://stackoverflow.com/questions/6547219/how-to-bind-function-arguments

Examples

f <- function(a, b) {
 return(a+b)
}

funcs <- createFunctionsList(FUN=f, param.name="b", values=c(1,2,3), func.names=c("plusone", "plustwo", "plusthree"))

funcs$plusone(2)
funcs$plusone(10)
funcs$plusthree(2)

A <- createRandomRegions(nregions=20, length.mean=10000000, length.sd=0, mask=NA)
B <- createRandomRegions(nregions=20, length.mean=10000000, length.sd=0, mask=NA)

 overlapsWith <- createFunctionsList(FUN=numOverlaps, param.name="B", values=list(a=A, b=B))
 overlapsWith$a(A=A) 
 overlapsWith$b(A=A)
