cerrejon: Cerrejon Core

In stratigraph: Toolkit for the plotting and analysis of stratigraphic and palaeontological data

Description

Pollen counts from the Cerrejon core. This is to illustrate how to read in ‘raw’ data in an arbitrary format, so it has been left entirely as character data.

Usage

data(cerrejon)

Format

A data frame with 189 observations (rows) of 113 variables (columns). The columns represent depths and the rows (after the first two) taxa; the data are raw counts.
