How to render HTML from RMarkdown without javascript in output

阅读更多关于 How to render HTML from RMarkdown without javascript in output

问题 Even the simplest rmarkdown document when rendered seems to create an html document that includes javascript. I am looking to create html that can be the body of an email. Is there a way to render markdown with no javascript in the resulting html? There is nothing special about the following, it is just a generic example: --- title: "Sample" author: "JKGrain" date: "March 31, 2015" output: html_document --- This is an R Markdown document. Markdown is a simple formatting syntax for authoring

Rmarkdown - how to remove grey background on output

阅读更多关于 Rmarkdown - how to remove grey background on output

I am experiencing a slightly irritating problem, which is that I am not able to remove the grey text from output (please see picture below). I've searched for a solution, but is restricted by my lack of knowledge about the proper terms, and therefore I am not able to find any solutions. I know this can be somehow bypassed by using only one "`", yet I need the triple "```" in order to run my code interpreting rows. The grey background on output --- title: "Untitled" output: word_document --- ```{r setup, include=FALSE} knitr::opts_chunk$set(echo = TRUE) ``` ```{r, echo=FALSE} hej <- ("test")

Is there a way to compile RMarkdown documents with datatables produced by DT outside of RStudio? I'm trying to include a datatable widget in an RMarkdown document that I then want to convert to html using knitr and pandoc. This works fine with RStudio but if I try to do the same with knitr and pandoc I'm unable to get a working html file. Here is a minimal example of an Rmd file that works with RStudio but not otherwise: --- title: "Minimal DT example" --- <style type="text/css"> table, table th, table td { border: none; } </style> ```{r} library(DT) datatable(iris) ``` Which I would then like

问题 I want to export a .Rmd file primarily as a latex pdf.

问题 I watched a great webinar by RStudio the other day about RMarkdown. After the webinar they posted the code used in the demonstrations online and I wanted to check out one example. I took their code, put it in my RStudio (which says it's fully up-to-date, v0.98.978), installed or updated all the necessary packages and hit "Run Document" I receive an error which I do not understand and for which Google has been very unhelpful.

Rmarkdown table with cells that have two values

阅读更多关于 Rmarkdown table with cells that have two values

I want to use rmarkdown to make a table where each cell has two values, for example 3.1 (0.05) or 78 ± 23.3 . These kinds of tables are pretty common in scientific literature ( like ones with bold values ), where we want to compactly show mean and standard deviation, or a value plus-minus some error term. So it would be useful to have a simple way to produce them when using Rmarkdown. For example: # my table mtcars mpg cyl disp hp drat wt qsec vs am gear carb Mazda RX4 21.0 6 160.0 110 3.90 2.620 16.46 0 1 4 4 Mazda RX4 Wag 21.0 6 160.0 110 3.90 2.875 17.02 0 1 4 4 Datsun 710 22.8 4 108.0 93 3
