Get mapunit ecological sites from Soil Data Access
get_SDA_coecoclass( method = "None", areasymbols = NULL, mukeys = NULL, query_string = FALSE, ecoclassref = "Ecological Site Description Database", not_rated_value = "Not assigned", miscellaneous_areas = TRUE )
aggregation method. One of: "Dominant Component", "Dominant Condition", "None". If "None" is selected one row will be returned per component, otherwise one row will be returned per map unit.
vector of soil survey area symbols
vector of map unit keys
TRUE return a character string containing query that would be sent to SDA via
"Ecological Site Description Database". If
NULL no constraint on
ecoclassref is used in the query.
Include miscellaneous areas (non-soil components)?
method="Dominant Condition" an additional field
ecoclasspct_r is returned in the result with the sum of
comppct_r that have the dominant condition
ecoclassid. The component with the greatest
comppct_r is returned for the
coecosite level information.
Note that if there are multiple
ecoclassid there may be more than one record per component.
