Description

Transform IUCN RedList conservation status to continuous values ranging from 0 to 5.

Usage

lets.iucncont(x, dd = NA, ne = NA)

Arguments

x	A vector or a matrix containing IUCN codes to be transformed.
dd	The value to be attributed to DD (data-deficient) species, the default option is NA.
ne	The value to be attributed to NE (not-evaluated) species, the default option is NA.

Value

Returns a vector/matrix with continuos values from 0 to 5.

EX and EW = 5

CR = 4

EN = 3

VU = 2

NT = 1

LC = 0
