When you hate paper and pens but still want to highlight stuff.
If you want this project to become better, please don’t hesitate to file an issue report or create pull requests. Thanks.
You can install highlightr from GitHub with:
# install.packages("devtools")
devtools::install_github("JBGruber/highlightr")You can use highlightr with different output formats:
If you run your code interactively (for example in RStudio), the
highlight function displays a html document in the Viewer pane (in
RStudio) or separate window:
library("highlightr")
library("tibble")
text <- c("This is a good test with some bad words", "bad guy vs good guy")
dict <- tibble(
feature = c("good", "bad"),
bg_colour = c("#2ca25f", "#de2d26")
)
highlight(text, dict)
If you place this code chunk in an RMarkdown document with output: html_document, the highlighted text will appear in the knitted HTML
output.
If you want to output a PDF, you need to include two LaTeX packages in
your header: xcolor and soul. You can do so in an RMarkdown
document with the argument header-includes like this:
---
output: pdf_document
header-includes:
- \usepackage{xcolor}
- \usepackage{soul}
---
```{r results='asis'}
library("highlightr")
library("tibble")
text <- c("This is a good test with some bad words", "bad guy vs good guy")
dict <- tibble(
feature = c("good", "bad"),
bg_colour = c("#2ca25f", "#de2d26")
)
highlight(text, dict, output = "tex")
```
