FreeFlowLinks: FreeFlowLinks

In holstius/Rcaline: Line source dispersion modeling using CALINE

Description

Construct a FreeFlowLinks object from a SpatialLinesDataFrame.

Usage

FreeFlowLinks(spobj, vehiclesPerHour, emissionFactor, width, height = 0,
  classification = LinkType(0), ...)

Arguments

spobj	a SpatialLinesDataFrame object
vehiclesPerHour	average number of vehicles per hour (also known as "flow")
emissionFactor	emissions per vehicle, in grams per mile (per hour)
width	mixing zone width, in meters
height	elevation above ground level (not sea level!)
classification	see LinkType for possible values
...	other arguments

Details

vehiclesPerHour, emissionFactor, and other arguments can all be specified as expressions. Use them the same way you would use arguments to transform. A FreeFlowLinks object can be plotted with plot or coerced to a data.frame with as.data.frame.

Value

a FreeFlowLinks object
