bdc_quickmap {bdc}R Documentation

Create a map of points using ggplot2

Description

Creates a map of points using ggplot2 useful for inspecting the results of tests implemented in the bdc package.

Usage

bdc_quickmap(
  data,
  lat = "decimalLatitude",
  lon = "decimalLongitude",
  col_to_map = "red",
  size = 1
)

Arguments

data

data.frame. Containing geographical coordinates. Coordinates must be expressed in decimal degree and in WGS84.

lat

character string. The column name with latitude. Coordinates must be expressed in decimal degree and in WGS84. Default = "decimalLatitude".

lon

character string. The column with longitude. Coordinates must be expressed in decimal degree and in WGS84. Default = "decimalLongitude".

col_to_map

character string. Defining the column or color used to map. It can be a color name (e.g., "red") or the name of a column of data. Default = "blue"

size

numeric. The size of the points.

Details

Only records with valid coordinates can be plotted. Records missing or containing invalid coordinates are removed prior creating the map.

Value

A map of points created using ggplot2.

Examples


decimalLatitude <- c(19.9358, -13.016667, -19.935800)
decimalLongitude <- c(-40.6003, -39.6, -40.60030)
.coordinates_out_country <- c(FALSE, TRUE, TRUE)
x <- data.frame(decimalLatitude, decimalLongitude, .coordinates_out_country)

bdc_quickmap(
  data = x,
  lat = "decimalLatitude",
  lon = "decimalLongitude",
  col_to_map = ".coordinates_out_country",
  size = 1
)
