Remove any rows which show sharp shifts in velocity that are likely due to tracking errors
Usage
remove_vel_anomalies(
obj_name,
target = "velocity",
method = "gesd",
alpha = 0.05,
max_anoms = 0.2
)
Arguments
- obj_name
The input viewr object; a tibble or data.frame with attribute
pathviewr_steps
that includes"viewr"
- target
The column to target; defaults to "velocity"
- method
The anomaly detection method; see anomalize::anomalize()
- alpha
The width of the "normal" range; see anomalize::anomalize()
- max_anoms
The max proportion of anomalies; see anomalize::anomalize()
Value
A viewr object (tibble or data.frame with attribute
pathviewr_steps
. Rows in which large anomalies were detected have
been removed. No additional columns are created.
Details
This function runs anomalize::anomalize() on a per-trajectory basis. The separate_trajectories() and get_full_trajectories() must be run prior to use.
