Read metadata from a Tucson-format chronology file.

Share:

Description

This function includes improvements to the read_crn function from the dplR library. The principle changes are better parsing of metadata, and support for the Schweingruber-type Tucson format. Chronologies that are unable to be read are reported to the user. The user (or read_crn) must tell the function whether the file is a Schweingruber-type chronology.

Usage

read_crn_metadata(file, SCHWEINGRUBER)

Arguments

SCHWEINGRUBER

Is the file in the Schweingruber-type Tucson format?

Details

Value

A data.frame containing the metadata.
