fd_inventory_summary()

Value

A data.frame or tibble. See "Details" for column descriptions.

Details

The returned columns are as follows:

  • replicate (character): Replicate code, extracted from SubplotID.

  • plot (integer): Plot ID number, extracted from SubplotID.

  • subplot (character): Subplot code, extracted from SubplotID.

  • ba_m2_ha (numeric): Basal area, square meters per hectare.

  • stocking_ha (numeric): Stocking, trees per hectare.

Note

For now this is pretty basic. More detailed summaries could be made, e.g. by live/dead, species, etc.
