Get map unit properties from Soil Data Access
Description
Get map unit properties from Soil Data Access
Usage
get_SDA_property(
property,
method = c("Dominant Component (Category)", "Weighted Average", "Min/Max",
"Dominant Component (Numeric)", "Dominant Condition", "None"),
areasymbols = NULL,
mukeys = NULL,
WHERE = NULL,
top_depth = 0,
bottom_depth = 200,
FUN = NULL,
include_minors = FALSE,
miscellaneous_areas = FALSE,
query_string = FALSE,
dsn = NULL
)
Arguments
property
character vector of labels from property dictionary tables (see details) OR physical column names from component or chorizon table.
method
one of: "Dominant Component (Category)", "Dominant Component (Numeric)", "Weighted Average", "MIN", "MAX", "Dominant Condition", or "None". If "None" is selected, the number of rows returned will depend on whether a component or horizon level property was selected, otherwise the result will be 1:1 with the number of map units.
areasymbols
vector of soil survey area symbols
mukeys
vector of map unit keys
WHERE
character containing SQL WHERE clause specified in terms of fields in legend or mapunit tables, used in lieu of mukeys or areasymbols. With aggregation method "NONE" the WHERE clause may additionally contain logic for columns from the component and chorizon table.
top_depth
Default: 0 (centimeters); a numeric value for upper boundary (top depth) used only for method="Weighted Average", "Dominant Component (Numeric)", and "MIN/MAX"
bottom_depth
Default: 200 (centimeters); a numeric value for lower boundary (bottom depth) used only for method="Weighted Average", "Dominant Component (Numeric)", and "MIN/MAX"
FUN
Optional: character representing SQL aggregation function either "MIN" or "MAX" used only for method="min/max"; this argument is calculated internally if you specify method="MIN" or method="MAX"
include_minors
Include minor components in "Weighted Average" or "MIN/MAX" results? Default: TRUE
miscellaneous_areas
Include miscellaneous areas (non-soil components) in results? Default: FALSE. Now works with all method types)
query_string
Default: FALSE; if TRUE return a character string containing query that would be sent to SDA via SDA_query
dsn
Path to local SQLite database or a DBIConnection object. If NULL (default) use Soil Data Access API via SDA_query().
Details
The property argument refers to one of the property names or columns specified in the tables below. Note that property can be specified as either a character vector of labeled properties, such as "Bulk Density 0.33 bar H2O - Rep Value", OR physical column names such as "dbthirdbar_r". To get "low" and "high" values for a particular property, replace the _r with _l or _h in the physical column name; for example property = c("dbthirdbar_l","dbthirdbar_r","dbthirdbar_h"). You can view exhaustive lists of component and component horizon level properties in the Soil Data Access "Tables and Columns Report".
