Internal / Helper functions of package ROptEst for function robest
Description
These functions are internally used helper functions for robest,
in package ROptEst.
Usage
.dynScopeEval(expr)
.constructArg.list(fun,matchCall, onlyFormal=FALSE, debug =FALSE)
.fix.in.defaults(call.list, fun, withEval=TRUE)
.pretreat(x, na.rm = TRUE)
.check.eps(...)
.isOKsteps(steps)
.isOKfsCor(fsCor)
Arguments
expr
an expression.
fun
function, a matched call of which is manipulated.
matchCall
a return value of a call to match.call.
onlyFormal
logical; shall arguments not explicitely contained in
the formals of fun be kept in the matched call?
debug
logical: if switched on, issues information for debugging.
call.list
a list of matched arguments drawn from a call to match.call
applied to fun which is to be supplemented by defaults of
not-yet-matched formals.
withEval
logical: shall arguments be evaluated?
x
input data x of robest or roptest.
na.rm
logical: if TRUE, the estimator is evaluated at
complete.cases(x).
...
input from robest or roptest from which to conclude
on radiuses.
steps
number of steps to be used in kStep estimator in robest.
fsCor
argument fsCor of robest.
Details
.dynScopeEval marches up the stack of calls to evaluate an expression,
hence realizes dynamical scoping.
.constructArg.list takes a function fun and the return value
of match.call and, as return value, produces a list of arguments where
the formal arguments of fun are set to their default values and
with extra item esc.
If argument onlyFormals is TRUE and the formals contain ...,
the returned list only contains formal arguments of fun, filled with
default values from the definition where available, and, in addition,
in element esc a list with element one of the original matched call
and, as subsequent elements, with the named, evaluated arguments of the
matched call which are no formal arguments of fun.
If argument onlyFormals is FALSE or the formals do not contain
..., the returned list again contains formal arguments of fun
filled in with defaults where available, but in addition it contains the arguments
of the matched calls non matched to formals (in particular those passed on through
...). Then element esc in the returned list with contains
element one of the original matched call coerced to list, i.e., the name of
the called function.
.fix.in.defaults takes a list of arguments of fun taken from a
matched call obtained by match.call from within a call of fun
(after coercing to list) and supplements this list by formal arguments of
fun which are not yet matched but have default arguments (with exactly
these default values). The return value is the prolongated list.
.pretreat, if is.numeric(x) is FALSE, coerces x
to a numeric matrix (by a call to data.matrix in case
x is a data.frame, respectively, by a call to as.matrix else.
If na.rm is TRUE, x is reduced to na.omit(x).
The return value is a list of elements x, the possibly modified
input x, and completecases, the return value of
compeletecases(x).
.check.eps takes its input (possibly empty in part)
and returns a list eps with elements sqn, e,
lower, and upper. Necessarily the input ... must
contain an argument matching to x, and sqn is the square root
of either the length of x (if x is a vector) or the number of
columns of x (in case dim(x)==2). In case ... contains
none of the elements eps, eps.lower, eps.upper, elements
lower and upper of the return value are set to 0 and
0.5, respectively. Else, if eps is contained input ...
element e of the return list is set to eps, and
lower and upper are left empty. Otherwise, element e
of the return list is left empty and lower and upper are filled
with eps.lower and eps.upper from input ... if available
and else with default values 0 and 0.5, respectively.
.isOKsteps checks whether argument steps is a valid
argument, i.e., is an integer larger than 0 of length 1 and, accordingly,
returns TRUE or FALSE.
.isOKfsCor checks whether argument fsCor is a valid
argument, i.e., larger than 0 and of length 1 and, accordingly,
returns TRUE or FALSE.
