stat_hurricane: Hurricane

In fmax85/hurricane: Storm observations geom

Description

stat_hurricane computes a specific data frame of coordinates required by geom_hurricane. It contains the geographical points corresponding to the four quarters of circle, specified by the origin point of the storm and the wind radii in the four quadrants, for each wind speed level. The destPoint function is adopted to generate the points representing the quarters of circles.

Usage

stat_hurricane(mapping = NULL, data = NULL, geom = "polygon",
  position = "identity", na.rm = FALSE, show.legend = NA,
  inherit.aes = TRUE, ...)

Examples

# When using `stat_hurricane`, you will typically need a storm
# observation data frame, with specific columns. You can find a
# test dataset along with this package named `ike`. Consider
# the following code as a test example:

## Not run: 
library(ggplot2)

ike_1 <- ike %>% dplyr::filter(latitude > 29 & latitude < 30)
plot <- ggplot(data = ike_1, mapping = aes(x = longitude, y = latitude)) +
stat_hurricane(mapping = aes(x = longitude, y = latitude, r_ne = ne, r_se = se, r_sw = sw,
                             r_nw = nw, colour = wind_speed), alpha = 0) +
theme_minimal()

## End(Not run)
