CalcBoundaryConvex: Calculate Boundary Convexity
In rLFT: Processing Linear Features

Description Usage Arguments Details Value

Cpp function that calculates convexity of a single feature.

CalcBoundaryConvex(
  feature,
  windowSize,
  stepSize,
  fid,
  rid,
  filename = "",
  noRID = TRUE
)

`feature`	A NumericMatrix that holds the data of one feature from the given sf object.
`windowSize`	A double describing the diameter of the window used to measure convexity.
`stepSize`	A double describing the distance between measurements along an arc.
`fid`	An integer that holds the current feature id.
`rid`	A string that holds the unique route ID for the current feature.
`filename`	A string denoting the name of the file you wish to output convexity data to.
`noRID`	A boolean that denotes whether the given sf object has an RID column.

Cpp function that takes in a single feature from the given sf object and calculates raw convexity, convexity index, and sinuosity of that feature. It formats convexity data into a NumericMatrix and outputs it.
