Method returning attributes of an object of class generic_spct or derived,
or of class waveband. Only attributes defined and/or set by package
'photobiology' for objects of the corresponding class are returned. Parameter
which
can be used to subset the list of attributes.

Vectors of character strings passed as argument to which
are
parsed so that if the first member string is "-"
the remaining
members are removed from the allowed
; and if it is "="
the
remaining members are used if in allowed
. If the first member is
none of these three strings, the behaviour is the same as if the first
string is "="
. If which
is NULL
all the attributes in
allowed
are used. The string ""
means no attributes, and has
precedence over any other values in the character vector. The order of the
names of annotations has no meaning: the vector is interpreted as a set
except for the three possible "operators" at position 1.
