Description

Add a multi-sided polygon to a plot.

Usage

addWindBarbs(
  x,
  y,
  speed,
  dir,
  circleSize = 1,
  circleFill = "transparent",
  lineCol = 1,
  extraBarbLength = 0,
  barbSize = 1,
  ...
)

Arguments

x	vector of longitudes
y	vector of latitudes
speed	vector of wind speeds in knots
dir	wind directions in degrees clockwise from north
circleSize	size of the circle
circleFill	circle fill color

station1 <- cefa_load(nwsID = 451702, meta = cefaMeta) %>% raws_filterDate(20100623, 20100623)
station2 <- cefa_load(nwsID = 452319, meta = cefaMeta) %>% raws_filterDate(20100623, 20100623)
