horizon_column_spec.Rd

Returns the schema for the horizons data.table carried by a PedonRecord: an ordered named list mapping column names to their R type ("numeric" or "character"). Adding a new attribute means editing this single function.

Usage

horizon_column_spec()

Value

Named list of column types in canonical order.

Examples

spec <- horizon_column_spec()
head(names(spec))
#> [1] "top_cm"                "bottom_cm"             "designation"          
#> [4] "boundary_distinctness" "boundary_topography"   "munsell_hue_moist"
