I am trying to title a histogram in R Markdown with a title involving Latex. However, I can't get it to work. Here is my format in code chunk for R Mark down:
hist(X, freq = FALSE, breaks = 115, main="Blah Blah $MATH$")
hist(X, freq = FALSE, breaks = 100, main="Blah Blah $MATH$")
Any recommendations ?
In the context of R Markdown documents, I would actually strongly urge you to use figure captions rather than plot titles, like so:
---
title: "Stack Overflow Answer"
author: "duckmayr"
output: pdf_document
---
```{r histogram, fig.cap="Blah Blah $\\mathcal{MATH}$"}
hist(islands, main = "")
```
You can use subfigures, which is the normal LaTeX way.
Then you'll use the fig.subcap chunk option rather than fig.cap:
title: "Stack Overflow Answer"
author: "duckmayr"
header-includes:
- \usepackage{subcaption}
output: pdf_document
---
```{r histogram, fig.cap="Histograms", fig.subcap=c("Blah Blah $\\mathcal{MATH}$ (islands)", "Blah Blah $\\mathcal{MATH}$ (linx)"), out.width="45%"}
hist(islands, main = "")
hist(lynx, main = "")
```
You can add (limited) latex with latex2exp
install.packages("latex2exp")
You could use it like this:
library("latex2exp")
hist(islands, main =TeX('$\\alpha^5 - \\beta$'))
Which would look like:
Best is you take a look at the documentation page what kind of Latex formatting is possible with the package.
