Old globe projection methods — globeproj • fmesher

Deprecated globe projection methods that may be removed in the future

Usage

old_globeproj(
  type = NULL,
  orient = NULL,
  xlim = NULL,
  ylim = NULL,
  scale = NULL
)

.globeproj.types(x, ...)

old_outline(x, add = FALSE, do.plot = TRUE, ...)

old_graticule(x, n = c(24, 12), add = FALSE, do.plot = TRUE, ...)

old_tissot(x, n = c(12, 6), add = FALSE, do.plot = TRUE, ...)

old_limits(x, loc = NULL, ...)

old_project(x, loc, inverse = FALSE, ...)

Arguments

type: Projection type, see .globeproj.types()
orient: long,lat,rotation
xlim: x-axis limits
ylim: y-axis limits
scale: x- and y- scaling factors
x: A globeproj object
...: Additional parameters passed on to other methods
add: logical; If TRUE, add to existing plot
do.plot: logical; If TRUE, do plotting
n: The number of Tissot indicatrices (n-long, n-lat) to compute
loc: Coordinates to be mapped.
inverse: logical

Value

A vector of names of available projection types; "longlat", "mollweide", "hammer", "orthocyl", "lambert", "gall-peters"

A list:

xlim: X axis limits in the map domain
ylim: Y axis limits in the map domain

Functions

.globeproj.types(): Types of globe projections
old_limits(): Calculates projection axis limits
