So I have a vignette, vignettes/test-vignette3.Rmd : --- title: "Sample Document" output: html_document: highlight: kate theme: spacelab toc: yes pdf_document: toc: yes --- Header ========= When I hit the knit HTML button, I get the following: processing file: test-vignette3.Rmd output file: test-vignette3.knit.md Output created: /tmp/RtmpKVpegL/preview-5ef42271c0d5.dir/test-vignette3.html However, if I copy this file to inst/doc and hit the knit HTML button, I get: processing file: test-vignette3.Rmd output file: test-vignette3.knit.md Output created: test-vignette3.html My questions are: How

I am using R markdown to create a PDF R course. I want to insert a quiz like the following: --- output: pdf_document --- What is the class of the following R object? 1. `pi` ```{r} class(pi) ``` Which, as expected, creates a PDF with this content: However, I would like the reader to not have such an easy access to the answer. These are the ideas I've had so far to achieve this: Paint the answer and code white, so the reader would have to select the text to see the answer; Include a tooltip that would work on mouse over question. Flush the answer to the end of the document; Setting the answer

Before Christmas I previously asked single style sheet across multiple knitr documents . I now know that the key search term I was missing is "child document". I have created a minimal markdown example but I am getting headers in the created document that are part of the knitting process. I am using RStudio to process it. I have seen many similar questions, but none of the answers work. I have tried various combinations of the chunk parameters and so far to no avail. Question: How do I get rid of the header from the final knitted document? # Master document ```{r master1, comment='', echo

I am new to writing R packages. I'm trying to learn how to make a vignette for my package. I have created a vignettes folder with a file "getting-started.Rmd" --- title: "WaterML Tutorial" author: "Jiri Kadlec" date: "`r Sys.Date()`" output: rmarkdown::html_vignette vignette: > %\VignetteIndexEntry{Introduction to the WaterML R package} %\VignetteEngine{knitr::rmarkdown} %\VignetteEncoding{UTF-8} --- ## Quick Start This simple example shows how to get started with the <my R package>. To build the vignette I use the command: devtools::build_vignettes() Then I run Rcmd.exe INSTALL my_package ,

I had succesfully used knit_child for generating pdf files, following the code of http://yihui.name/knitr/demo/child/ , but when I try to use that example in a .Rmd file: ```{r, results='asis', echo=FALSE, message=FALSE} out = NULL for (p in c("p1","p2","p3","p4","p5","p6","p7","p8","p9","p10")) { out = c(out, knit_child('quick_variable.Rmd')) cat(out) } ``` (I modify the original code, for work in Rmd ). I have two problems, the first one: | | | 0% | |... | 5% ordinary text without R code | |....... | 11% label: unnamed-chunk-4 (with options) List of 1 $ echo: logi FALSE | |.......... | 16%

I am using Knit PDF to compile a beamer presentation in RStudio. --- title: "A.P. Statistics" author: "Notes for Chapter 3.Rmd" date: "Monday, October 13, 2014" output: beamer_presentation --- ## Computer Output ```{r} summary(lm(cars$dist~cars$speed)) ``` How can I change the font size (just for this one chunk, leaving other chunks the same font size) so that the output of this command fits on one slide? One solution is using knitr hooks . A hook is code that will run before or after the chunk code is executed. You could use it to insert a LaTeX fontsize command in the file. ```{r echo=FALSE}
