    Introduction

    Please read the vignette.

    Or, after installation, the help page:

    help("treePlotArea-package", package = "treePlotArea")
    #> Correction Factors for Tree Plot Areas Intersected by Stand Boundaries
    #> 
    #> Description:
    #> 
    #>      The German national forest inventory uses angle count sampling, a
    #>      sampling method first published by Bitterlich (1947) and extended
    #>      by Grosenbaugh (1952) as probability proportional to size
    #>      sampling. When plots are located near stand boundaries, their
    #>      sizes and hence their probabilities need to be corrected.
    #> 
    #> Details:
    #> 
    #>      You will find the details in
    #>      'vignette("An_Introduction_to_treePlotArea", package =
    #>      "treePlotArea")'.
