View movements on an interactive map

view_spatial is a simple wrapper that displays movement tracks on an interactive mapview or leaflet map.

Usage

view_spatial(
  m,
  render_as = "mapview",
  time_labels = TRUE,
  stroke = TRUE,
  path_colours = NA,
  path_legend = TRUE,
  path_legend_title = "Names",
  verbose = TRUE
)

Arguments

m

move2 object. Can contain a column named colour to control path colours (see details).

render_as

character, either 'mapview' to return a mapview map or 'leaflet' to return a leaflet map.

time_labels

logical, whether to display timestamps for each track fix when hovering it with the mouse cursor.

stroke

logical, whether to draw stroke around circles.

path_colours

character, a vector of colours. Must be of same length as number of individual tracks in m and refers to the order of tracks in m. If undefined (NA) and m contains a column named colour, colours provided within m are used (see details). Othwersie, colours are selected from a standard rainbow palette per individual track.

path_legend

logical, wether to add a path legend from m or not. Legend tracks and colours will be ordered by the tracks' temporal apperances, not by their order in m.

path_legend_title

character, path legend title. Default is "Names".

verbose

logical, if TRUE, messages and progress information are displayed on the console (default).

Value

An interactive mapview or leaflet map.

Details

If argument path_colours is not defined (set to NA), path colours can be defined by adding a character column named colour to m, containing a colour code or name per row (e.g. "red". This way, for example, column colour for all rows belonging to individual A can be set to "green", while column colour for all rows belonging to individual B can be set to "red". Colours could also be arranged to change through time or by behavioral segments, geographic locations, age, environmental or health parameters etc. If a column name colour in m is missing, colours will be selected automatically. Call colours() to see all available colours in R.

if (FALSE) { # \dontrun{
library(moveVis)
library(move2)

data("move_data", package = "moveVis")

view_spatial(move_data)
 
# return a leaflet map (leaflet must be installed)
view_spatial(move_data, render_as = "leaflet")
 
# turn off time labels and legend
view_spatial(move_data, time_labels = FALSE, path_legend = FALSE)
} # }
