object
A Spectra
object
safe
Logical. If TRUE, data is being added to the object using a
SQL join (using a key field given by the key
option), otherwise it is
assumed the order of the rows is consitent with the order of the rows in
object
key
Character, name of the column of the
data.frame storing the ids for the SQL join. Ignored if safe
is
FALSE
.
exclude_id
Logical, if TRUE
, ids
used for the SQL join are removed from the data slot after the join.

exclude_id
Logical. For
the features
method, if TRUE
, the spectra ids are added to the

that is returned. For the "features<-"
method, If
TRUE
, ids used for the SQL join are removed from the data slot after
the join.
append
Logical, if TRUE
, the data is
appended to any existing data. if FALSE, the data provided is erasing any
existing data.
