See kosukeimai/qss for other supplementary materials and the original data sets.
The website for this package is available at https://kosukeimai.github.io/qss-package
qss is not available from CRAN, install the package from github with:
# if you have not installed the `devtools` package
# install.packages("devtools")
library("devtools")
install_github("kosukeimai/qss-package", build_vignettes = TRUE)
To list all data sets contained in this package:
data(package = "qss")
data(elections, package = "qss") # load the elections data
vignette(package = "qss") # list all vignettes
browseVignettes("qss") # list vignettes and R code
vignette("causality", package = "qss") # show the vignette for the Causality chapter
The Federalist papers text files are in the extdata/federalist directory of the installed package and need to be accessed as follows:
library("tm")
federalist_dir <- system.file("extdata", "federalist", package = "qss")
dir(federalist_dir)
corpus.raw <- Corpus(DirSource(federalist_dir))
corpus.raw
In 1.3.5 "Data Files", several types of data files are discussed. These are included in extdata/:
library("foreign")
dir(system.file("extdata", "data_files", package = "qss"))
load(system.file("extdata", "data_files", "UNpop.RData", package = "qss"))
read.csv(system.file("extdata", "data_files", "UNpop.csv", package = "qss"))
read.dta(system.file("extdata", "data_files", "UNpop.dta", package = "qss"))
To rebuild README.md from README.Rmd:
rmarkdown::render("README.Rmd")
The site for the package is built using pkgdown:
# devtools::install_github("hadley/pkgdown")
pkgdown::build_site()
