R plots in code chunks are first recorded via a graphical device in knitr, and then written out to files. fig.align: The alignment of plots. Create professional reports that document our workflow and results directly from our code, reducing the risk of accidental copy and paste or transcription errors. For example: You can provide a figure caption using fig.cap in the chunk options. However, I've been running into the following issues: Some code chunks have long texts that I'm using to... 1 Like.

Automatically wrap tables and code from Typora's markdown format to PDF. A highly surprising fact to LaTeX beginners is that figures float by default: even if you generate a plot in a code chunk on the first page, the whole figure environment may float to the next page. A code chunk will appear: Inside the code chunk you can write and run R-code. #Wrap long lines: Long lines in the output will not be (hard-)wrapped automatically unless you break them manually. R Markdown is a low-overhead way of writing reports which includes R code and the code’s automatically-generated output. results: When set to 'hide', text output will be hidden; when set to 'asis', text output is written “as-is,” e.g., you can write out raw Markdown text from R code (like cat('**Markdown** is cool.\n')). R Markdown is a variant of Markdown that has embedded R code chunks, to be used with knitr to make it easy to create reproducible web-based reports. ref.label NULL A character vector of labels of the chunks from which the code of the current chunk is inherited.
