plot_data: Plot location of sampling data

In James-Thorson/VAST: Vector-Autoregressive Spatio-Temporal (VAST) Model

Plot location of sampling data

Description

plot_data produces diagnostics plots for the spatial distribution of data and knots

Usage

plot_data(
  Extrapolation_List,
  Spatial_List,
  Data_Geostat = NULL,
  Lat_i = Data_Geostat[, "Lat"],
  Lon_i = Data_Geostat[, "Lon"],
  Year_i = Data_Geostat[, "Year"],
  PlotDir = getwd(),
  Plot1_name = "Data_and_knots.png",
  Plot2_name = "Data_by_year.png",
  col = "red",
  cex = 0.1,
  pch = 19,
  year_labels,
  projargs = "+proj=longlat",
  map_resolution = "medium",
  land_color = "grey",
  country = NULL,
  ...
)

Arguments

Extrapolation_List	Output from Prepare_Extrapolation_Data_Fn
Spatial_List	Output from Spatial_Information_Fn
Data_Geostat	data-frame of data (with columns 'E_km', 'N_km', 'Year', 'Lon', 'Lat' at a minimum)
PlotDir	Directory for plots
year_labels	character vector specifying names for labeling times t_i
projargs	Character passed to CRS and see that documentation for description. See https://proj.org/operations/projections/index.html for a list of projections to pass via projargs. As a stable default please consider projargs='+proj=natearth +lon_0=0 +units=km' where argument +lon_0 allows the user to center eastings on a specified longitude.
land_color	color for filling in land (use land_color=rgb(0,0,0,alpha=0) for transparent land)
country	a character vector of country names.
...	addition inputs to plot
