paleofire (version 1.2.4)

potveg: potveg

Description

Retrieve potential vegetation types based on charcoal sites location

Usage

potveg(ID, classif = "rf99", buffer = NULL)

Arguments

ID

An object of the class "pfSiteSel"

classif

Potential vegetation to be used: "rf99" in reference to Ramankutty and Foley (1999) or "l12" in reference to Levavasseur et al. 2012.

buffer

Distance in m that defines a radius around each site to calculate the dominant vegetation type by kernel density estimation.

Value

An object of the class "potveg" i.e. a list contaning two data frames: "site_data" for charcoal sites and associated potential vegetation type, "map" data frame used for mapping data. See plot.potveg for details.
