Description Usage Arguments Value See Also

Imports csv file holding field recorded data returning a list holding field and other key data provided as arguments.

Field measures to be taken on logs and branches include:

Azimuth (azimuth): mean angle of orientation of the branch or log measured from the base of the tree (usually with magnetic north as reference, measured clockwise), mandatory
Diameter at base (dBase): diameter at insertion point on the stem, for branches, diameter of the lower section for logs, mandatory
Diameter at top (dTip): always 0 for branches, diameter of the higher section for logs, defaults to 0, mandatory only for logs
Length (length): length of logs or branches, mandatory for logs, mandatory for branches only if their slenderness coefficient is to be computed
Distance (tipD): length of branch or log projection on the ground, starting from tree base to tip of branch or log, mandatory
Height (height): height of branch insertion on the stem or height of lower section of the log, to be used to compute z coordinate of CM, defaults to NA, mandatory only for z determination of CM
Tilt (tilt): mean branch tilt or log tilt from the horizontal plane (eg a vertical branch is 90 degrees, an horizontal branch is 0 degrees), to be used to compute z coordinate of CM, defaults to 0, mandatory only for z determination of CM. Note however that the tree tip should be considered as a branch, not a log, in order to account for foliage biomass. In this case the tilt value should be recorded otherwise it would default to 0, ie an horizontal branch
To be pruned (toBePruned): a boolean value, defaults to FALSE, optional
Path to tip (pathToTip): a boolean value TRUE on logs and branches that make part of the “main stem” of the tree, defaults to FALSE, optional

`fileName`	Name of csv file holding field data
`dst`	Fresh density of wood of the tree
`branchesAllometryFUN`	the function that should compute branch biomass from its diameter
`bCM`	Estimated position of the centre of mass of branches, a real number from 0.01 (CM at branch base) to 1.00 (CM at branch tip). As a rule of thumb, average live branches, with an average amount of foliage, have CM approx. from 1/3 to 2/3 of their length. bCM = 1.0 (default value)
