plotStreamlines

Description

Plot the estimated vectorfields as streamlines using the metR package

Usage

plotStreamlines(
  VF,
  features,
  display.image = T,
  size.arrow = 1.5,
  surface = T,
  color_stream = "black",
  n = NULL,
  dt = NULL,
  grid = c(50, 50),
  gamma.u = 0.2,
  gamma.v = 0.2,
  arrow.angle = 25,
  arrow.length = 0.6,
  min.L = 2,
  L = 50,
  color.extern = NULL,
  res = 2,
  pt.size = 3,
  pt.alpha = 0.8,
  S = 10,
  jitter = 1,
  skip = 2.5,
  xwrap = NULL,
  ywrap = NULL
)

Arguments

VF	Data.frame estimated bei the SPATAwrappers::runVectorFields function
color_stream	Color of the stream lines
n	optional numeric indicating the number of points to draw in the x and y direction (replaces skip if not NULL)
dt	optional numeric size "timestep" for integration
grid	The grid size for estimation
gamma.u, gamma.v	Gamma for stream estimation
arrow.angle	Angle for arrows
min.L	minimum length of segments to show
L	typical length of a streamline in x and y units
color.extern	Add extra external colors (the colname of the external numeric feature, needs to be in VF data.frame)
res	resolution parameter (higher numbers increases the resolution)
pt.size	Numeric pointsize
pt.alpha	Numeric Alpha of points
S	optional numeric number of timesteps for integration
jitter	parameters passed to grid::arrow
skip	numeric specifying number of gridpoints not to draw in the x and y direction
xwrap, ywrap	vector of length two used to wrap the circular dimension.
