r-markdown

问题 I wanted to use RStudio (Version 0.99.903) and knitr to convert a .Rmd file (please see below) to a PDF file. --- title: "test" output: pdf_document --- Roses are \textcolor{red}{red}, violets are \textcolor{blue}{blue}. When I run "Knit PDF" I got the following error message: processing file: test.Rmd output file: test.knit.md ! Undefined control sequence. l.87 Roses are \textcolor pandoc.exe: Error producing PDF Error: pandoc document conversion failed with error 43 In addition: Warning

问题 I have some R code to plot an ellipse for a bivariate normal with known mean and variance using the ellipse() function from the mixtools package. However when I run this in Rmarkdown I get an error saying "plot.new has not been called yet". When I put another plot directly above it in the same chunk it runs but otherwise I get the error. What's the reason for this? plot(ellipse(params,covariance, npoints = 500, alpha=0.01), xlim = c(-2,3.5), ylim = c(0,.75), xlab="alpha", ylab = "beta") This

问题 I use the knitr::opts_chunk$set(fig.align = "center") at the beginning of the rmarkdown document to set the alignment of figures. When I output HTML files, the static figures are aligned to the center, but the HTML widgets, such as outputs from leaflet() and ggplotly() have the default alignment (to the left). Is there an option to force the HTML widgets to the center? EDIT: example given below. --- title: "test" output: html_document --- ```{r setup, include=FALSE} knitr::opts_chunk$set(echo

问题 I am working on an automated report using R Markdown which shows retention profile plots for which I am querying data from Redshift. Since I need to ssh into my connection I figured I'd add my ssh commands as a bash command in my markdown script. I checked to make sure simple commands work (e.g., cd, mkdir) which all work fine but it seems to get stuck on the ssh command. Does anybody have an idea whether this does not work because of the ssh command or because of R markdown/ knitr (it works

问题 bookdown::gitbook() adds the content of https://github.com/rstudio/bookdown/tree/master/inst/resources/gitbook as a htmltools::htmlDependency . How can I add such a custom dependency to a gitbook? The goal is to provide an easy way to add a corporate css (including images). The definition of the htmlDependency() and all the required files would reside in an R package. 回答1: The ... arguments of bookdown::gitbook() are eventually passed to rmarkdown::html_document() , which are further passed

问题 I have many tables to create and am trying to create them in a loop. I'm using flextable with rmarkdown inside rstudio. Using print(theFlextable) command in a loop produces a list of text rather than the table. This happens for docx and html output types. If I don't use a loop flextable renders correctly. Here is a demo: --- title: "Demo" output: word_document --- ```{r setup, include=FALSE} library(flextable) ``` ## This Works ```{r iris, echo=F, message=F, error=F, results='asis'} ft<

问题 I have a R Markdown/knittr document that generates pairs of plots and tables. The number of pairs is variable, so I create them inside of a loop. I would like the results to be interleaved in the output: table 1, plot 1, table 2, plot 2... In the example below, all tables come first at the top of the document. I have tried various permutations of pander or kable as my table function wrapping the table function in print or leaving it bare with or without results='asis' EDIT: I found a solution

问题 How do you hide rendered shiny output? Specifically, I have some figures/tables generated by shiny and I have a button, that when clicked should hide the figures/tables, and when clicked again should show them. This is what I have so far (below), and it works somewhat, but where it's supposed to hide the renderPlot output, there is a big blank space in the document that I am trying to make go away. It should be possible to just copy and paste this code into Rstudio and hit run document (it's

问题 I created a technical report in .rmd in RStudio with much math expression. With knit to html, it worked very well. As html file cannot rendered well on GitHub repository, I changed my .rmd output to github_document (.md) file. However, when I upload the file onto GitHub, I found formulas cannot be shown correctly. They are in the latex script format. I was wondering which is a valid strategy to upload a rendered .rmd file (in RStudio) into a GitHub repository? (Not GitHub Pages). Thank you.
