Resolve a ccp (crop calendar period) string with whitespace and dash normalisation

Source: R/crop_lookup.R
resolve_ccp.Rd

Handles common variations between user input and the canonical English value stored in coef_time$ccp:

  • Trims outer whitespace and collapses internal multiple spaces.

  • Replaces en-dash (U+2013) and em-dash (U+2014) with hyphen.

  • Case-insensitive match.

Usage

resolve_ccp(x, table = NFert::coef_time)

Arguments

x

Character. The ccp string to resolve.

table

Lookup with column ccp; default NFert::coef_time.

Value

The canonical ccp string (as in table$ccp), or x unchanged with a warning if not found.

Examples

resolve_ccp("Spring-summer crop 100\u2013130 days")  # em-dash
#> [1] "Spring-summer crop 100-130 days"
resolve_ccp("autumn-winter crop <150 days")         # case
#> [1] "Autumn-winter crop <150 days"
