r-markdown

问题 Not even sure if this is possible, but is there a way to extract only the raw text portion of the .Rmd file and discard any code? Or basically converting an .Rmd file into .txt file within R? I've tried the function readLines , but this makes a huuuuuge character with all kinds of (to me) useless meta-data. 回答1: You can knit document without evaluating and including code. Here's an example of dummy document foo.Rmd : # Header 1 foo ## Header 2 bar ## Header 22 foobar ```{r} 1 ``` text text

问题 How can I suppress the bullet points in front of the TOC items in the created HTML file? I want to see only the headline numbers... Example Test.Rmd file: --- title: "Untitled" author: "Author" date: "01/25/2015" output: html_document: number_sections: true toc: yes toc_depth: 3 --- *Content* # Headline 1 ## Sub headline 1.1 ## Sub headline 1.2 ### Sub sub headline 1.2.1 # Headline 2 The TOC of the resulting HTML document will look like this (with the unwanted bullet points - here indicated

问题 I am looking to create a table in a PDF document using rmarkdown , knitr and pander . The table should be nearly identical to Table 1 shown below, except the asterisks should be bullets. Is this at all possible using only the R libraries listed above? Here is my code to produce the PDF document (and thus the table above): --- title: "xxx" author: "xxx" date: "xxx" output: word_document: default pdf_document: fig_height: 4 fig_width: 10 highlight: tango geometry: margin=3cm --- ```{r global

问题 I'm trying to show a wordcloud2 wordcloud, but it only works in an html-knitted Rmd file. This works: --- title: "Untitled" output: html_document --- ```{r wordcloud} library(wordcloud2) wordcloud2(demoFreq) ``` But this does not: --- title: "Untitled" output: pdf_document --- ```{r wordcloud} library(wordcloud2) wordcloud2(demoFreq) ``` It will knit with always_allow_html: yes in the YAML, but the wordcloud doesn't show up: --- title: "Untitled" output: pdf_document always_allow_html: yes --

问题 I am new to knitr and markdown and this is my first question asked. Maybe this question has a simple answer that I just can't find. I have a for-loop, which creates 3 ggplots. The loop runs 300 to 400 times depending on the data input. I want to define the size of these 3 pictures as: 1st picture: width = 7, height = 3 2nd picture: width = 7, height = 3 3nd picture: width = 7, height = 12 So far I am using the following code: ```{r calc, echo=FALSE, warning=FALSE, message=FALSE, results='asis

问题 I'd like to cite an article in my figure caption. I've tried using the Rmarkdown/pandoc [@citekey] and the latex \\citep{citekey} forms in the fig.cap chunk option without any luck. Here is a reproducible example: --- output: rmarkdown::tufte_handout references: - id: Nobody06 title: 'My Article' author: - family: Nobody given: Jr issued: year: 2006 --- Some text [@Nobody06]. ```{r figure, fig.cap="A figure [@Nobody06]"} library(ggplot2) qplot(1:10, rnorm(10)) ``` # References This produces

问题 I'm trying to generate an HTML report using RStudio, R Markdown and knitr. In the report I would like to display some bash code. I do not want to run the code but I would like it to be highlighted. It has been mentioned in another question but the suggestion there doesn't work for me. Here's what I've tried so far: --- title: "bash highlighting?" output: html_document --- ```{r, engine = 'bash', eval = FALSE} for foo in (ls bar) do echo $foo done ``` ```{bash, eval = FALSE} for foo in (ls bar

问题 Following this question (including a interactive 3D figure with knitr) and this example by Yihui (https://dl.dropboxusercontent.com/u/15335397/misc/webgl-rmd.html), I can include a 3D interactive figure in html output using knitr and Rmarkdown. But I would like to include a static figure in word/pdf output. Is it possible to do this? Thanks for any suggestion.

问题 In my R Markdown documents, I sometimes want to just generate a report without showing the actual code (specially when I send it to my boss). How can I hide the R code and just show the graph and results? For example: --- output: html_document --- ```{r fig.width=16, fig.height=6} plot(cars) ``` This shows both the commands and the plot. How can I remove the commands from my HTML report? 回答1: Sure, just do ```{r someVar, echo=FALSE} someVariable ``` to show some (previously computed) variable

问题 I have the following R Markdown script called test.Rmd : --- params: results: value: !r mtcars --- ```{r setup, echo=FALSE, include=FALSE} df <- params$results knitr::kable(df) ``` When I run the following in OpenCPU: library(rmarkdown) library(knitr) rmarkdown::render("test.Rmd", output_format = "html_document") Error in yaml::yaml.load(yaml, handlers = knit_params_handlers(evaluate = evaluate), : unused argument (eval.expr = TRUE) I installed different versions of YAML and it didn't fix the
