## calendarHeat: An R function to display time-series data as a calendar heatmap 

CTJohnson

To transform the currently opened Graphviz source file (in DOT Language) into a PNG:

{
    "cmd": [ "dot", "-Tpng", "-o", "$file_base_name.png", "$file"],
    "selector": "source.dot"
}

Usage

CTJohnson

Use public data, t, and csvkit to find Congressmembers on Twitter from the command-line

This snippet uses:

• t, a command-line tool for accessing the Twitter API
• csvcut from the invaluable csvkit suite
• a CSV of U.S. congressmember data compiled by the Sunlight Foundation, from the public unitedstates/congress-legislators Github project.

First, download the CSV (included below in this gist as sunlight-legislators.csv:

library(rgeos)
library(rgdal) # needs gdal > 1.11.0
library(ggplot2)

# map theme
devtools::source_gist("https://gist.github.com/hrbrmstr/33baa3a79c5cfef0f6df")

map = readOGR("readme-swiss.json", "cantons")
map_df <- fortify(map)
