make_map: Produce Oakland map of continuous variable with gradient...

In Changing-Cities-Research-Lab/oakViz: What the Package Does (One Line, Title Case)

Description

This function takes in data and produces a census tract map of Oakland representing the variable using a gradient color scale. Census tract column must be named "tractid10".

Usage

make_map(
  data,
  var,
  shp_tracts,
  palette = "sequential",
  jenksbreaks = T,
  neg_bins = 3,
  pos_bins = 3,
  breaks = scales::extended_breaks(n = 7),
  labels = scales::percent,
  limits = NULL,
  coord = F,
  save = F,
  savename = "plot.png",
  caption = paste0(frb_caption, ses_caption, period_caption)
)

Arguments

data	Data with a column containing census tracts and variable of interest.
var	Name of column containing variable to plot.
shp_tracts	"US_tract_2010.shp" loaded object
palette	Color palette: "sequential" (default) or "diverging"
jenksbreaks	Uses Jenks breaks when T, otherwise uses continuous color scale
neg_bins	For Jenks breaks, number of negative color bins. Default is 3.
pos_bins	For Jenks breaks, number of positive color bins. Default is 3.
breaks	Gradient scale breaks, either numeric vector or scales::extended_breaks(n = 6)
labels	Gradient scale labels, either character vector or scales::percent or scales::comma
limits	Manual limits for color scale, numeic vector: c(min, max)
coord	T if plotting coordinate values (lat, lon). Default is F.
save	T if user would like to return plot object and save file, F (default) to just return object.
savename	File name of map for saving.
caption	Figure caption

Value

Map of variable of interest.
