untag: Remove tags

In photobiology: Photobiological Calculations

Remove tags

Description

Remove tags from an R object if present, otherwise return the object unchanged.

Usage

untag(x, ...)

## Default S3 method:
untag(x, ...)

## S3 method for class 'generic_spct'
untag(x, byref = FALSE, ...)

## S3 method for class 'generic_mspct'
untag(x, byref = FALSE, ...)

Arguments

x	an R object.
...	ignored (possibly used by derived methods).
byref	logical indicating if new object will be created by reference or by copy of x

Value

if x contains tag data they are removed and the "spct.tags" attribute is set to NA, while if x has no tags, it is not modified. In either case, the byref argument is respected: in all cases if byref = FALSE a copy of x is returned.

Methods (by class)

• untag(default): Default for generic function

• untag(generic_spct): Specialization for generic_spct

• untag(generic_mspct): Specialization for generic_spct
