Knitr will treat each option that you pass to knitr::opts_chunk$set as a global default that can be overwritten in individual chunk headers.
Easy markdown slideshows code#
To set global options that apply to every chunk in your file, call knitr::opts_chunk$set in a code chunk. See the R Markdown Reference Guide for a complete list of knitr chunk options.
fig.height, fig.width The width and height to use in R for plots created by the chunk (in inches). warning = FALSE prevents warnings that are generated by code from appearing in the finished. message = FALSE prevents messages that are generated by code from appearing in the finished file. 
echo = FALSE prevents code, but not the results from appearing in the finished file.R Markdown still runs the code in the chunk, and the results can be used by other chunks. include = FALSE prevents code and results from appearing in the finished file.Here are some of the most common arguments:

R Markdown comes to rescue! It provides an authoring framework for data science.

If the data changes, the author must repeat the entire process to update the graph. The author may take a deep breath when the report is finally well-shaped. The author makes the graph/table, saves it as a file, and then copy and pastes it into the final report. Consider how people typically create an analytical report. R Markdown combines the core syntax of Markdown and embedded R code chunks that are run so their output can be included in the final document. What makes markdown distinct is that it is both machine-readable and human-readable. It is young compared to the other markup languages. Rather than writing complex markup code (e.g. LyX, XML, HTML or LaTeX), Markdown enables the use of a syntax much more like plain-text email. HTML is an example of a widely known and used markup language. The code used to specify the format are called tags. The language specifies code for formatting, both the layout and style, within a text file. Markup languages are designed for the processing, definition, and presentation of text. Markdown is a lightweight markup language designed to make authoring content easy for everyone.
