BuildAgeTable: Builds a data.frame holding an age table

In mbask/treeglia: Stem-analysis on tree cross-sections

Description

Builds a data.frame holding generic data for each cross-section. There will be as many rows as the number of cross-sections. The data.frame can be saved in a csv file through ExportFile.

Usage

BuildAgeTable(RWdata, Tree.object)

Arguments

RWdata	a data.frame holding the set of ring-widths. It can be imported from a csv text file through ImportRW. In case of broadleaf trees, the age table must be computed on the ring-width set of the main stem.
Tree.object	a data.frame holding tree data. This object is easily created through BuildTreeObject.

Value

Returns a data.frame holding cross-sections heights as rownames. For each cross-section, the first column holds the number of rings counted, the second column holds the its radius (as the sum of the full set of ring-widths), the third column holds its age (the tree age minus number of rings) when its tip got to the cross-section level. Tree age is computed as the number of rings on the lowest cross-section.
