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; } /* center the widget */ div.leaflet-control-container { margin: auto !important; } </style> but if I

I have a chunk of SQL in my R Markdown / Notebook Document: ```{sql output.var = "df"} SELECT * FROM FakeData WHERE Date >= '2017-01-01 ``` It takes literally 5 minutes to run. Is there an easy way to cache the result of the query without Knitting the document or writing the file to a CSV. I'd perhaps like the cache to live for a couple of hours, or maybe a day (is there a way to adjust this as well?) If you put cache=TRUE in the chunk options and you are working in rStudio, you can select a section of code and run it directly using the green arrows in the upper right of the rMarkdown/knitr

I am trying to use RMarkdown (Knit) for the first time to produce pdf. The default file (File > New File > R Markdown) works well, it shows the generated pdf when compiled. For example, the following code runs, ```{r cars} summary(cars) ``` However, if I just change cars with "myData," it does not compile and shows, Error in object[[i]] : object of type 'closure' is not subsettable Calls: <Anonymous> ... withVisible -> eval -> eval -> summary -> summary.default Execution halted I have "myData" loaded in the global-environment and can do other operations in original R script. Can someone please

I'm searching and trying to add a image as watermark to rmarkdown pdf, I'm using the render function to generate the PDFs, and saw the \usepackage{draftwatermark} and this question: Watermark in rmarkdown But they don't help me in adding a image as watermark. --EDIT-- I achieved what I wanted putting this to the header of .Rmd: header-includes: - \usepackage{eso-pic,graphicx,transparent} And placing this in the start of file (before the rest of .Rmd): \AddToShipoutPictureFG{ \put(0,0){% \parbox[b][\paperheight]{\paperwidth}{% \centering {\transparent{0.3} \includegraphics[width=\paperwidth

I am trying to include a .png file in a file that I am rendering using bookdown. knitr::include_graphics() should be the way to go. The code: ```{r fig1, fig.cap='My Caption', echo=FALSE, message=FALSE, warning=FALSE} knitr::include_graphics("./Figures/My Figure.png") ``` In the .Rmd file, I can run my r block, and it renders the image below. So, the path should be correct. However, when I knit the chapter, or render the entire book, the figure is not rendered. Could it be that some of my other options are overriding the figure? Below are my YAML header of the index.Rmd file, and the code in

I'm basing my rmarkdown -Jekyll-Blog off of Yihui's fantastic boilerplate for using servr::jekyll() , which in turn wraps knitr . Because I want to use citations (via pandoc-citeproc , wrapped by rmarkdown ) I need to use rmarkdown::render , not knitr to, well, render the *.md s. As per the servr manual, I understand that rmdv2() should do the job, which essentially wraps/modifies jekyll() : The functions rmdv1() and rmdv2() are similar to jekyll(), and the only difference is the way to compile R Markdown documents: rmdv1() uses the markdown package (a.k.a R Markdown v1) via knit2html(), and

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. In the YAML section where LaTeX packages can be included, add the caption package: header-includes: - \usepackage{caption} Then at the beginning of the RMarkdown document body add: \captionsetup
