问题 Is it possible to embed a YouTube video in a R Markdown? So far what I have is <a href="http://www.youtube.com/watch?feature=player_embedded&v=Q8rakpF7duU " target="_blank"><img src="http://img.youtube.com/vi/Q8rakpF7duU/0.jpg" alt="IMAGE ALT TEXT HERE" width="240" height="180" border="10" /></a> but it only adds an image.

问题 I am developing an R Markdown Shiny document to: Subset a data frame to include the "date" column and some numeric data columns. The way the shiny user input is set up, you select radio buttons for the data columns to include, then hit the "Subset Data" button to create d() - NO PROBLEM:) Generate a list of plots ( plotList ), one for each numeric data column (plotted against the date column).

问题 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

问题 I am generating a PDF document with Rmarkdown, within which I want to manually define figure numbers . Below is an example of a chunk: ```{r chunk26, fig.cap = "Fig. 5.3 My figure caption"} plot(1, 1) ``` I use a special numbering to follow the chapters of my document. The problem is that when I knit the PDF, "Figure X:" is automatically added before each caption. As a result, my figure captions look like this example: Note I have used the following parameters in the beginning of my rmarkdown

问题 I am a beginner in using Markdown (I am using it with R studio and knitr). I am struggling with a point that I hope you would be able to help me to figure it out. I would like a chunk to be evaluated only if the output_format of the rmarkdown document is pdf. In other words, the chunk option "eval" automatically set to TRUE if the knitr output was selected as "knitr PDF". Otherwise, eval = FALSE. In your view, what is the most straightforward way to do this. Many thanks in advance 回答1: Try

问题 When I use kableExtra for a PDF output, the table renders beautifully, BUT gives an error if there isn't another, non-kable extra table in the program. Has anyone else seen this behavior? the file appears to knit fine, but then throws an error in pandoc?
