drop_it_like_its_bot: drop_it_like_its_bot

Description Usage Arguments Value Author(s) Examples

Description

Detects guilty bots in Mturk data based on Qualtrics lat/long coordinates, then drops them returning "clean" dataset

Usage

1
  drop_it_like_its_bot(lat, long, dat, remove_suspect = "all", more=NULL)

Arguments

lat

Column name (character) of survey latitude coordinate, typically generated via Qualtrics

long

Column name (character) of survey longitude coordinate, typically generated via Qualtrics

dat

data.frame() object, housing survey responses, probably downloaded from Qualtrics

remove_suspect

Character string, with options: "all", "keep_first", "more_than". Default = "all". "all" drops any overlap, "keep_first", drops duplicates, "more_than" drops rows with lat/long overlaps greater than the specified criterion

more

Numeric, indicating the number of rows to exclude if greater than a certain number (e.g., Lat 45.44993 appears more than 3 times). Default is NULL; only use if specificying "more_than" to remove_suspect argument.

Value

Returns dataframe() cleaned of all rows fitting "more_than" criterion. Users should then examine lat/long overlaps. Turk IDs, IP addresses, and demographics may all be different, but more than a few responses from the exact same lat/long coordinates seems unlikely. Users can then examine these cases for botness with various validity checks.
