Methods for class "unitname".
# S3 method for unitname
print(x, ...)
# S3 method for unitname
summary(object, ...)
# S3 method for unitname
rescale(X, s, unitname)
# S3 method for unitname

harmonise(..., coerce=TRUE, single=FALSE)
# S3 method for unitname
harmonize(..., coerce=TRUE, single=FALSE)For print.unitname the value is NULL.
For summary.unitname the value is an object of class
summary.unitname (with its own print method).
For rescale.unitname the value is another object of class "unitname".
For compatible.unitname the result is logical.
For harmonise.unitname the result is a list of
identical unitnames if single=FALSE (the default),
or a single unitname if single=TRUE.
Objects of class "unitname" representing
units of length.
Other arguments.
For print.unitname these arguments are passed to
print.default.
For summary.unitname they are ignored.
For compatible.unitname and harmonise.unitname these arguments
are other objects of class "unitname".
Conversion factor: the new units are s times the old units.
Optional new name for the unit. If present, this overrides the rescaling operation and simply substitutes the new name for the old one.
Logical. If TRUE, a null unit of length is compatible with
any non-null unit.
Logical value indicating whether to return a single unitname, or a list of unitnames.

These are methods for the generic functions
print, summary, rescale
and compatible
for the class "unitname".
An object of class "unitname" represents a unit of length.
The print method prints a description of the unit of length,
and the summary method gives a more detailed description.
The rescale method changes the unit of length by rescaling it.
The compatible method tests whether two or more units of length
are compatible.
The harmonise method returns the common unit of length
if there is one. For consistency with other methods for
harmonise, the result is a list of unitname objects,
with one entry for each argument in .... All of these
entries are identical. This can be overridden by setting
single=TRUE when the result will be a single unitname object.
