This function attempts to automatically detect and correct inconsistent locations (for instance due to a writing error) in trajectory tables.

fixLocErr(x, s = 15, spline = FALSE)

Arguments

x

A trajectory data table as produced by the makeTraj function.

s

The discrmination threshold of the outlier detection algorithm. Higher values correspond to less outliers.

spline

If spline is TRUE, inconsistent locations are estimated using spline interpolation. If FALSE (the default), a linear interpolation is used instead.

Value

A trajectory data table as produced by the makeTraj function. If not present, an "error" column will be added that indicates which observations were corrected.
