问题 How do you suppress captions for a texreg table? I'm using Rmarkdown to generate a LaTeX file. Here's a simple example: ```{r, echo=FALSE, message=FALSE, results="asis"} library(texreg) data <- data.frame(a=c(1,2,3,4), b=c(6,3,4,4)) texreg(lm(a~b, data=data), caption="", custom.note="", float.pos="h!") ``` The table I get has a caption on the bottom that says "Table 1:". How do I get rid of it? Thanks. 回答1: In the YAML section where LaTeX packages can be included, add the caption package:

问题 I'm currently trying to setup a hugo blog with blogdown and can't find a way to add feature or thumbnail images to posts from within .Rmd files, which would like this with the tranquilpeak theme: As far as I understand, it is easy to do in .md files by just adding some syntax like this: +++ featuredImage = "img/foobar.jpg" +++ I found this in the minos theme and in a discourse post. But how can I do this inside a .Rmd file? 回答1: It does not matter whether you use .md or .Rmd: if the theme

问题 I want to create an html document with a centered leaflet widget inside it. --- title: "Exemple" author: "Antoine Bichat" date: "31/08/2018" output: html_document --- ```{r leaflet, fig.align="center"} library(leaflet) leaflet() %>% addTiles() %>% addMarkers(lng=174.768, lat=-36.852, popup="The birthplace of R") ``` The first idea with fig.align="center" doesn't work. I found this question and I adapted it to my case: <style> /* resize the widget container */ .leaflet { width: 80% !important;

问题 I have an Rmarkdown document which I'm outputting to Word and I'm trying to insert a company logo to the top of the page, above the header that includes the title and author. I haven't found a solution to this. I've tried using pandoc_args to --include-in-header , but this wasn't successful. I'm not confident that I was using it correctly though. Is it possible to include an image above the header? --- title: "Untitled" author: "r.bot" date: "Thursday, January 1, 2015" output: word_document:

问题 --- title: "Untitled" output: html_document --- ```{r setup, include=FALSE} library(DT) xsx = function(){ print(getOption("viewer")) print(datatable(data.frame(d =1))) 1 } xsx() ``` Inside xsx() function, DT widgets will not be rendered in HTML result. How can I get widgets print inside a function? 来源： https://stackoverflow.com/questions/35567124/how-to-print-htmlwidgets-to-html-result-inside-a-function

问题 This is similar to Xaringan issue #29. I'm setting up a Xaringan template to be used at work, and I want to keep all the CSS and Javascript files in the same location. I don't want anyone to have to copy the same files into each presentation directory. However , I also don't want to refer to a common root directory. I could (I think) point to our in-house Bitbucket server, but I would much rather analysts and data scientists be able to get the files from their local repo (for speed, and also

问题 I'm trying to increment the section headers in my rMarkdown (PDF output) file by 1. Instead of # First resulting in 1 First , I'd like 2 First. I found a way to define the offset in html_output using the following syntax, but it doesn't work for pdf_output. --- title: "Untitled" author: "author" date: "date" output: html_document: toc: true pandoc_args: [ "--number-sections", "--number-offset=1" ] --- # First Header # First SubHeader This results in 2 First Header 2.1 First Subheader However,

问题 I am using R notebook to preview the file. Even though all the code is in one chunk, a line gets separated into two. Would you please tell me how I can resolve this? As you can see all the code is in one chunk. However, when I run this chunk, it gets separated into two. I am not sure if it matters but here is the code I am running. library(MASS) par(mfrow=c(3,1)) hist(galaxies, breaks=500) hist(galaxies, breaks=100) hist(galaxies, breaks=50) Also here are the versions of R and RStudio. I an

问题 Working with Rmarkdown in Rstudio , using pandoc and knitr , I am targetting PDF output via LaTeX and HTML output with MathJax . I would like to use some of the MathJax extensions that are available, to allow richer LaTeX for the PDF target. Specifically, I am trying to use the siunitx extension right now, although I am also interested in others (e.g. physics ). Using siunitx works fine with LaTeX for PDF output, but I've had a hard time getting it working with HTML output. Here an example

问题 I'm trying to write a memo on R Markdown syntax and as such I'd like to include in the document's output the R Markdown code and the output. To be clear, I'd like the output to look something like: ~~~~~~~~~~~~~~~~~~ Including the following code chunk in the document: ```{r, eval=FALSE} summary(cars) ``` will produce the following output: summary(cars) ~~~~~~~~~~~~~~~~~~ I'm failing to escape the ``` and the {r, eval=FALSE} . 回答1: Maybe if you evaluate this: ```{r comment=NA} cat("```{r, eval
