Usage

sample_map(
  metadata,
  mode = 1,
  map_params = list(),
  group = NULL,
  point_params = list(),
  label = NULL,
  label_params = list(),
  shp_file = NULL,
  crs = 4326,
  xlim = NULL,
  ylim = NULL,
  add_scale = TRUE,
  scale_params = list(),
  add_north_arrow = TRUE,
  north_arrow_params = list()
)

crs coordinate: https://asa-blog.netlify.app/p/r-map/#crs

xlim

xlim

ylim

ylim

add_scale

add annotation_scale

scale_params

parameters parse to ggspatial::annotation_scale

Value

map

Examples

data(otutab)
anno_df <- metadata[, c("Id", "long", "lat", "Group")]
colnames(anno_df) <- c("Id", "Longitude", "Latitude", "Group")
if (requireNamespace("ggspatial")) {
  sample_map(anno_df, mode = 1, group = "Group", xlim = c(90, 135), ylim = c(20, 50))
}
