Create data for fitting an occupancy model
createOccuData.RdThis function takes generic occupancy site data and, optionally, visit data without species observations, adds detection data for a species in a given year, runs some checks and formats the output.
Arguments
- config
A list of configuration parameters see
configPipeline- sp_code
SAFRING_No of the species of interest as extracted from ABAP. Ignored if download set to FALSE.
- years
A numeric vector with elements corresponding to the years we want data for. Ignored if download set to FALSE.
- site_data
A dataframe with occupancy site data.
- visit_data
Optional. A dataframe with occupancy visit data.
Value
A list containing two data frames: one with site data and one with
visit data, if visit data is provided. The second element will be NULL if visit
data not provided. Note that if visit_data is provided then all the sites without
visits will be removed - i.e., both site and visit data frames will have the same
set of sites.
