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 |
