harmonise.fv
Make Function Tables Compatible
Convert several objects of class "fv"
to the same values of the function argument.
Usage
"harmonise"(..., strict=FALSE)
"harmonize"(..., strict=FALSE)
Arguments
 ...

Any number of function tables (objects of class
"fv"
).  strict

Logical. If
TRUE
, a column of data will be deleted if columns of the same name do not appear in every object.
Details
A function value table (object of class "fv"
) is
essentially a data frame giving the values of a function $f(x)$
(or several alternative estimates of this value)
at equallyspaced values of the function argument $x$.
The command harmonise
is generic. This is the
method for objects of class "fv"
.
This command makes any number of "fv"
objects compatible,
in the loose sense that they have the same sequence of values of
$x$. They can then be combined by cbind.fv
,
but not necessarily by eval.fv
.
All arguments ...
must be function value tables
(objects of class "fv"
).
The result will be a list, of length equal to the number of
arguments ...
, containing new versions of each of these functions,
converted to a common sequence of $x$ values.
If the arguments were named (name=value
) then the return value
also carries these names.
The range of $x$ values in the resulting functions
will be the intersection of the ranges of $x$ values
in the original functions.
The spacing of $x$ values in the resulting functions
will be the finest (narrowest) of the spacings of the
$x$ values in the original functions.
Function values are interpolated using approxfun
.
If strict=TRUE
, each column of data will be retained only if
a column of the same name appears in all of the arguments ...
.
This ensures that the resulting objects are strictly compatible
in the sense of compatible.fv
,
and can be combined using eval.fv
or collapse.fv
.
If strict=FALSE
(the default), this does not occur,
and then the resulting objects are not guaranteed to be compatible
in the sense of compatible.fv
.
Value

A list, of length equal to the number of arguments
...
,
whose entries are objects of class "fv"
.
If the arguments were named (name=value
) then the return value
also carries these names.
