hampel filter

Description

detect outliers in bearings using hampel filter in a moving time window

Usage

hampel_time(path_to_data, col, k, t0 = 0.5, animal)

Arguments

`path_to_data`	string, dpath to file containing bearings
`col`	string, string indicating the column containing bearings
`k`	numeric, window size n seconds
`t0`	numeric,threshold for median filter. A high threshold makes the filter more forgiving, a low one will declare more points to be outliers. Default=0.5
`animal`	list, list generated by initAnimal functiom

Examples

#projroot<-paste0(getwd(),"/tRackIT_test_data/")
#animal <- getAnimal(projroot, animalID = "woodpecker")
#bearings <- list.files(animal$path$bearings, full.names = TRUE)
#lapply(bearings, function(x) hampel_time(path_to_data = x, col = "linear", animal = animal, k = 10))
