library("printr")
An R package containing the datasets used in
Kosuke Imai. 2017. Quantitative Social Science: An Introduction. Princeton University Press.
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
:

The site for the package is built using pkgdown:
