Get Soil Color Data from a local NASIS Database

Get, format, mix, and return color data from a NASIS database.

Usage

get_colors_from_NASIS_db(
  SS = TRUE,
  method = "dominant",
  mixColors = FALSE,
  dsn = NULL
)

Arguments

SS

fetch data from Selected Set in NASIS or from the entire local database (default: TRUE)

method

Aggregation method to handle multiple colors per horizon and moisture state. Default "dominant" for dominant condition (or first record) within moisture state. Other options include "mixed" to calculate mixture using simplifyColorData() and "none" to do no aggregation (returns a long format representation that may have multiple values per horizon and moisture state)

mixColors

Deprecated. See method. Should mixed colors be calculated where multiple colors are populated for the same moisture state in a horizon? Default FALSE takes the dominant color based on colorpct or first record based on horizon ID (phiid) sorting for "moist" and "dry" state. Pedon Horizon Color records without a moisture state populated are ignored.

dsn

Optional: path to local SQLite database containing NASIS table structure; default: NULL

Value

A data.frame with the results.
