Barplot comparing sites on 1 indicator, based on full output of ejamit() easy high-level function for getting a quick look at top few sites

Usage

ejam2barplot_sites(
  ejamitout,
  varname = "pctlowinc",
  names.arg = NULL,
  main = "Comparison of Sites",
  xlab = "Sites",
  ylab = NULL,
  sortby = NULL,
  topn = 5,
  ...
)

Arguments

ejamitout

list like output of ejamit(), where one element is table of sites, one row per site, column names at least varname (and "ejam_uniq_id" if names.arg not specified)

varname

name of a column in results_bysite, bar height

names.arg

optional vector of labels on the bars, like short site names or IDs

main

optional, for barplot

xlab

optional, for barplot

ylab

optional, for barplot, plain English version of varname, indicator that is bar height

sortby

set to FALSE if you want to have no sorting, or to an increasing vector that provides the sort order

topn

optional, show only the top n sites – Does not show all sites by default – only shows top n sites.

...

passed to barplot()

Value

same as barplot()

Examples

# Quickly compare top few sites by population count nearby
out <- copy(testoutput_ejamit_10pts_1miles)
ejam2barplot_sites(out, "pop")

# Show all 10,
ejam2barplot_sites(out, "traffic.score", topn = 10, cex.names = 0.8)

# Sort by site id
ejam2barplot_sites(out, "blockcount_near_site", topn = 10,
  sortby = -1 * out$results_bysite$ejam_uniq_id)

# Plot a calculated variable
sites <- copy(out$results_bysite)
sites$log_traffic = log10(sites$traffic.score)
plot_barplot_sites(sites, "log_traffic", ylab = "Traffic Score (log10 scale)", topn = 10)

# On a large monitor, 100 sites with legible labels if the window is wide enough
ejam2barplot_sites(testoutput_ejamit_100pts_1miles, topn = 100, cex.names = 0.4)
