Fieldmap databaseR/load_data_vegetation.R
load_data_vegetation.RdThis function queries the given database to retrieve data on vegetation (ready for use in calculate_vegetation function).
load_data_vegetation(
database,
plottype = NA,
forest_reserve = NA,
processed = TRUE
)name of Fieldmap/Access database (with specific Fieldmap
structure) including path
possibility to select only data for a certain plot type, e.g. 'CP' for Circular plot or 'CA' for Core area (the default NA means that data from all plots are retrieved)
possibility to select only data for 1 forest reserve by giving the name of the forest reserve (the default NA means that data from all plots are retrieved)
Should only processed and surveyed data be added? Defaults to TRUE (yes).
Dataframe with vegetation data, containing columns as
total_herb_cover, total_shrub_cover, total_tree_cover,
total_soildisturbance_game,
date_vegetation (= date of vegetation survey),
year_main_survey (= year of vegetation survey), ....
