This function queries the given database to retrieve additional data on plots
to save in forresdat and link with the datasets that are saved there.
load_plotinfo(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 columns plot_id, plottype, forest_reserve,
period, year of dendrometric survey and information on
(1) whether there has been a dendro, deadwood, regeneration and/or
vegetation survey and (2) whether the data have been processed or not.
