ck_catalogue()) by sector, applicable standard (ETCCDI / ET-SCI /
agroclimatic / comfort / drought / energy), or a free-text search
across the function name, full name, and ETCCDI code.
Arguments
- sector
Character (length 1) or
NULL. Filter to indices tagged with this sector. Common values:"agriculture","health","water","energy".NULL(default) returns all rows.- standard
Character (length 1) or
NULL. Filter to indices under this standard. Common values:"ETCCDI","ET-SCI","ETCCDI-approx","agroclimatic","comfort","drought","energy".NULL(default) returns all rows.- search
Character (length 1) or
NULL. Free-text search; rows are kept where the term appears (case-insensitive) in the function name, the full name, or the ETCCDI code.
