{Using \texttt{knitr} and \LaTeX\ for literate lab notes} {Boris Veytsman} {One of Knuth's important insights was the concept of literate programming, where the prose is as important as the code. Now many scientists in different fields are having similar insights about their work. While the published papers have been always recognized as the works of literature, now we start to understand this with respect to lab notes, the lowly reports of our daily activity. This explains the new interest to notebook interfaces: from commercial programs like Matlab and Mathematica to free systems like Wxmaxima and Jupyter. In this talk I discuss the approach that uses \LaTeX\ and \texttt{knitr} for creating lab notes. I compare it with the available notebook interfaces and the the solutions based on Markdown.}
