Internationalization R knitr Figure caption label

Question

I want to generate a Latex document with knitr, but it does not allow me to change the label for the figure into my language. The code:

```{r rstudio, echo = FAL         


        

Answer 1

You can actually include LaTeX code directly within the Rmd file to alter the settings.

As this answer explains, names like "Figure" and "Contents" are stored in macros like \figurename and \contentsname. To change them, you have to change the definition of the respective macros using \renewcommand within your preamble:

\renewcommand{\figurename}{Fig.}
\renewcommand{\contentsname}{Table of Contents}

Here's a list of the "name macros" (and their default meaning) defined by the LaTeX standard classes article, book, and report:

• \abstractname [only article, report]: Abstract
• \appendixname: Appendix
• \bibname [only book, report]: Bibliography
• \chaptername [only book, report]: Chapter
• \contentsname: Contents
• \figurename: Figure
• \indexname: Index
• \listfigurename: List of Figures
• \listtablename: List of Tables
• \partname: Part
• \refname [only article]: References
• \tablename: Table

Here is a MWE for your scenario:

---
output:
  pdf_document: default
---
\renewcommand{\figurename}{YOUR LABEL}
\renewcommand{\tablename}{TABLE LABEL}

```{r Table, echo =FALSE}
knitr::kable(iris[1:5,], caption = "A table")
```

```{r pressure, echo=FALSE, fig.cap="Test Caption"}
plot(pressure)
```

Alternative Approach

The fantastic package bookdown expands a lot on the basics of RMarkdown and knitr. One thing the package allows you to set internalisation, as explained here.
