Arguments

user	a character string representing the user name to logging into 'GreenFeed' system
pass	a character string representing password to logging into 'GreenFeed' system
unit	numeric or character vector or list representing one or more 'GreenFeed' unit numbers. The order should match with "feedtimes" files
gcup	a numeric value representing the grams of pellets per cup.
start_date	a character string representing the start date of the study (format: "dmy")
end_date	a character string representing the end date of the study (format: "dmy")
save_dir	a character string representing the directory to save the output file
rfid_file	a character string representing the file with individual IDs. The order should be Visual ID (col1) and RFID (col2)
file_path	a character string or list representing files(s) with "feedtimes" from 'C-Lock Inc.'

Value

An Excel file with pellet intakes for all animals and days within the specified period is saved to save_dir. The file is named "Pellet_Intakes_YYYY-MM-DD_YYYY-MM-DD.csv".

Examples

# You should provide the 'feedtimes' file provided by C-Lock.
# it could be a list of files if you have data from multiple units to combine
path <- system.file("extdata", "feedtimes.csv", package = "greenfeedr")

# You must include the grams of pellets per cup based on the result obtained from the 10-drops test

# If the user include an rfid file, the structure should be in col1 AnimalName or Visual ID, and
# col2 the RFID or TAG_ID. The file could be save in different formats (.xlsx, .csv, or .txt).
RFIDs <- system.file("extdata", "RFID_file.csv", package = "greenfeedr")
