rsunlight vignette - Interface to Sunlight Labs APIs

rsunlight is an R package to search and retrieve data from the Sunlight Labs APIs.

Returned objects from functions are simple lists. That is, you likely will want to take output objects and make data.frames, vectors, matrices, etc. In future versions of rsunlight, I will return data.frame's when possible as those are easy to work with in R for beginners, though advanced users may prefer lists or raw responses from the API with lots of info, including header, etc.

Installation

devtools::install_github("ropengov/rsunlight")

library('rsunlight')

Plot data

library('ggplot2')
dat <- cw_timeseries(phrase = 'climate change')
ggplot(dat, aes(day, count)) + 
  geom_line() + 
  theme_grey(base_size=20)

Plot more data

dat_d <- cw_timeseries(phrase='climate change', party="D")
dat_d$party <- rep("D", nrow(dat_d))
dat_r <- cw_timeseries(phrase='climate change', party="R")
dat_r$party <- rep("R", nrow(dat_r))
dat_both <- rbind(dat_d, dat_r)
ggplot(dat_both, aes(day, count, colour=party)) + 
  geom_line() + 
  theme_grey(base_size=20) + 
  scale_colour_manual(values=c("blue","red"))
