The function fills in the existing column to hold outlier flags, and either overwrites the original file or outputs a data structure.

data,
iterations = 20,
sigma = 2,
grvi = FALSE,
snowflag = FALSE,
plot = FALSE,
internal = TRUE,
out_dir = tempdir()
)

sigma |
number of deviations to exclude outliers at |
grvi |
reverse the direction of the screening intervals to accomodate for GRVI outliers |
