tinttint (Eddelbuettel and Gilligan 2019) updates the look and feel of ‘Tufte’ documents for R. It combines the (html and pdf parts of the) excellent tufte package (Xie and Allaire 2018) with the Roboto Condensed font use and color scheme proposed by envisioned css plus minor style changes such as removal of italics—but remains otherwise true to the tufte package for R. Later additions are a book style and well as generalisation of the font handling allowing for Lato and Garamond fonts along with extended color selection.
The package name follows an old tradition and is recursive: tint is not tufte.
Full documentation is available in the longer PDF vignette, its Lato and Garamond variants (see below) as well as the longer HTML vignette. As these render to about two megabytes each, we no longer include them by default in the package as it swells the size of the installed package unnecessarily.
The margin can be used for arbirtrary ‘figure’ environments by using
the knitr option marginfigure along with
standard mathematical markup.
We know from the first fundamental theorem of calculus that for x in [a,b]: ddx(∫xaf(u)du)=f(x).
We can also add a ‘note’ using the standard pandoc
notation of text in square brackets following an hat symbol:
^[text here].1
Notes can also be added in-line using an R command and the
margin_note() function.
Some text. Note that this note is
unnumbered.
One feature of the tint / tufte packages are margin
figure such as the first one on the right. It was created by setting the
knitr option fig.margin=TRUE; the plotting
code itself is standard.
ggplot(mtcars, aes(wt, mpg)) +
geom_point(size=3, aes(colour=factor(cyl))) +
theme(legend.position="none")
Charts can also take advantage of the theme_tint() we
added; it owes a lot to a similar function in the ggtufte package (Arnold 2018Arnold, Jeffrey. 2018. Ggtufte: Themes and Geoms Implementing)
(but which conflicts in its font settings with our, so we simplified).
Its effect can be seen in the second figure. Note that the
legend-suppression has to come after theme_tint() as
changes are additive.
Figures can span across the entire page; this is enabled by using the
chunk option fig.fullwidth = TRUE. Using the default them
but conditioning by number of cylinders:
A full width figure.
Besides margin and full width figures, one can of course also include
figures constrained to the main column. This is the default type of
figures in the LaTeX/HTML output. A single figure with cylinders in
color and transmission not controlled for, and once again using
theme_tint():
A figure in the main column.
Since version 0.1.1, the Lato and Garamond font families can be used. See the package for details. In contrast to the default Roboto variant, the Lato variant uses
latexfonts:
- package: lato
options: default
- package: FiraMono
linkcolor: "0.3,0.3,0.6"The Garamond variant uses
latexfonts:
- package: newtxmath
options:
- cmintegrals
- cmbraces
- package: ebgaramond-maths
- package: nimbusmononarrow
This requires the fonts to be installed on the system on which the document is prepared. How to install additional fonts is beyond the scope of this note, see platform and font-specific help.
One can use Pandoc-style citations using the the Bibtext citation
identifier inside of square brackets: [@someone:1984]. In
pdf mode, the standard natbib features are also available
such as \citet{}, \citep{} and more.
The package, just like any other pandoc-driven use of
markdown, can also typset code directly. We showed this above with the
ggplot() example (using R formatting) and the font
declarations (using YAML formatting).
