Prepare points and lines for ggplot

Usage

gg(x, ...)

ggl(x, ..., d = 90, n = 1000)

Arguments

x

Spherical or vector orientation data

...

<data-masking> Name-value pairs. The name gives the name of the column in the output. The value can be:

A vector of length 1, which will be recycled to the correct length.
A vector the same length as the current group (or the whole data frame if ungrouped).
NULL, to remove the column.
A data frame or tibble, to create multiple columns in the output.

d

numeric. Cone angle (small circle radius) in degrees. 90 (the default) produces great circles.

n

integer. Resolution of line.

Value

data.frame

Examples

if (require("mapproj")) {
  x <- Plane(120, 85)
  ggstereo() +
    ggplot2::geom_point(data = gg(x), ggplot2::aes(x, y), color = "red") +
    ggplot2::geom_path(data = ggl(x), ggplot2::aes(x, y), color = "red")

  x2 <- Line(120, 5)
  ggstereo() +
    ggplot2::geom_point(data = gg(x2), ggplot2::aes(x, y), color = "darkgreen") +
    ggplot2::geom_path(data = ggl(x2, d = 8), 
    ggplot2::aes(x, y, group = group), color = "darkgreen")

  x3 <- Plane(137, 71)
  ggstereo() +
    ggplot2::geom_point(data = gg(x3), ggplot2::aes(x, y), color = "darkgreen") +
    ggplot2::geom_path(
      data = ggl(x3, d = 90),
      ggplot2::aes(x, y, group = group), color = "darkgreen", lwd = 1
    ) +
    ggplot2::geom_path(
      data = ggl(x3, d = 90 + 11),
      ggplot2::aes(x, y, group = group, color = "sde <90")
    ) +
    ggplot2::geom_path(
      data = ggl(x3, d = 90 - 11),
      ggplot2::aes(x, y, group = group, color = "sde >90")
    )
}
