reduce_seasons: Query data within two sampling periods

In mfidino/uwinr: An R package to query and summarize camera trap data from the Urban Wildlife Information Network (UWIN) database

Description

reduce_seasons queries data for a single season or between two seasons depending on how arguments are filled.

Usage

reduce_seasons(uwin_data = NULL, start = NULL, end = NULL)

Arguments

uwin_data	The list object returned from collect_tables.
start	A character vector that contains the first sampling period and year that you would like to query. start must be 4 characters long with the first two characters denoting the sampling season and the last two characters denoting the year (e.g., April 2017 would be "AP17").
end	A character vector that contains the last sampling period and year that you would like to query. start must be 4 characters long with the first two characters denoting the sampling season and the last two characters denoting the year (e.g., April 2017 would be "AP17"). If only querying one season of data end should be left as NULL.

Value

Returns the list object from collect_tables with data from either a single season (if end is left NULL) or with data that lie between the sampling periods specified in start and end. Note that this only queries data in the Visits, Photos, and Detections table within the Access database.
