Set attributes
setattribute.RdThis operator sets or deletes attributes of a dataset and writes the result to outfile. The new attributes are only available in outfile if the file format supports attributes. Each attribute has the following structure: [var_nm@]att_nm[:{s|d|i}]=[att_val|{[var_nm@]att_nm}] var_nm Variable name (optional). Example: pressure att_nm Attribute name. Example: units att_val Comma-separated list of attribute values. Example: pascal The value of var_nm is the name of the variable containing the attribute (named att_nm) that you want to set. Use wildcards to set the attribute att_nm to more than one variable. A value of var_nm of '*' will set the attribute att_nm to all data variables. If var_nm is missing then att_nm refers to a global attribute. The value of att_nm is the name of the attribute you want to set. For each attribute a string (att_nm:s), a double (att_nm:d) or an integer (att_nm:i) type can be defined. By default the native type is set. The value of att_val is the contents of the attribute att_nm. att_val may be a single value or one-dimensional array of elements. The type and the number of elements of an attribute will be detected automatically from the contents of the values. An already existing attribute att_nm will be overwritten or it will be removed if att_val is omitted. Alternatively, the values of an existing attribute can be copied. This attribute must then be enclosed in curly brackets. A special meaning has the attribute name FILE. If this is the 1st attribute then all attributes are read from a file specified in the value of att_val.
Usage
cdo_delattribute(ifile, attributes = NULL, ofile = NULL)
cdo_setattribute(ifile, attributes = NULL, ofile = NULL)
