Create plots and LaTeX tables that look like
SPSS output for use in teaching materials. Rather than
copying-and-pasting SPSS output into documents,
R code that mocks up SPSS output can be
integrated directly into dynamic LaTeX documents with tools
such as knitr.
Functionality includes statistical techniques that are typically covered
in introductory statistics classes: descriptive statistics, common
hypothesis tests, ANOVA, and linear regression, as well as box plots,
histograms, scatter plots, and line plots (including profile plots).
Package r2spss is on CRAN (The Comprehensive R Archive
Network), hence the latest release can be easily installed from the
R command line via
install.packages("r2spss")
To install the latest (possibly unstable) development version from
GitHub, you can pull this repository and install it from the
R command line via
install.packages("devtools")
devtools::install_github("aalfons/r2spss")
If you already have package devtools installed, you can
skip the first line.
LaTeX tables created with package r2spss
build upon several LaTeX packages. A LaTeX
style file that includes all requirements can be produced with function
r2spss.sty(). By default, it prints the content of the
style file on the R console, but its only argument
path can be used to specify the path to a folder in which
to put the file r2spss.sty. For instance, the following command
can be used to put the style file in the current working directory.
r2spss.sty(path = ".")
After putting the style file in the folder that contains your
LaTeX document, the following command should be included in
the preamble of your LaTeX document, i.e., somewhere in
between \documentclass{} and
\begin{document}.
\usepackage{r2spss}
Package r2spss is the most useful when writing dynamic
LaTeX documents with tools such as the R
package knitr. When
creating LaTeX tables in R code chunks with
knitr, the output of the chunk should be written directly
into the output document by setting the chunk option
results='asis'. For more information on knitr
chunk options, in particular various options for figures, please consult
the knitr
documentation.
Package r2spss can create output that mimics the look of
current SPSS versions, as well as the look of older
versions. The relevant functions contain the argument
version for specifying which type of output to create.
Possible values are "modern" to mimic recent versions and
"legacy" to mimic older versions. LaTeX tables
that mimic the look of recent SPSS version thereby build upon the
LaTeX package nicematrix and
its NiceTabular environment, which is preferred for its
seamless display of background colors in the table.
However, r2spss requires nicematrix version
6.5 (2022-01-23) or later. It is also important to note that tables
using the NiceTabular environment may require several
LaTeX compilations to be displayed correctly.
Within a dynamic LaTeX document or any other
R session, it can be useful to set a global preference for
which SPSS version to mimic. This can be done with the
accessor function r2spss_options$set(). For instance, a
default to mimic older SPSS versions can be set with:
r2spss_options$set(version = "legacy")
Various examples for using r2spss are given in the
package vignette, which can be accessed from the R console
with
vignette("r2spss-intro")
