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 equally-spaced 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`

.

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.
