arguSelect: Argument selection

Description

Arguments of specific functions are selected from arbitrary numbers and varieties of arguments.

Usage

arguSelect(rd = NULL, fun = c("mapply", "ringApply"), ...)

Value

list of selected arguments.

Arguments

rd

NULL or data.frame. Multilevel ecological data series. If NULL then this argument is ignored.

fun

character or NULL. Vector of function names.

...

Further arguments not necessarily contained in the processed function(s).

Details

Closures with ellipsis terms use this function to extract and pass arguments to other functions. Arguments in MoreArgs lists are also extracted and stored again as MoreArgs lists.

Examples

##Multilevel ecological data series of tree-ring widths:
data(Prings05,envir = environment())
## Radial increments measured on 2003:
data(Pradii03,envir = environment())    

## Selection of arguments in some functions:

                  mp = c(0.5,1),
                  rf.t = 2003)
str(ar1)

ar2 <- arguSelect(fn = 'amod',
                  only.dup = TRUE,
                  mp = c(0.5,1),
