r-markdown

问题 I used to be able to render images in r-markdown using a URL with the following code  but I get a file not found error ! LaTeX Error: File https://assets-cdn.github.com/images/modules/logos_page/GitHub-Mark' not found . Am I missing packages? This code still works on some shiny apps published a few month ago. Below the a working file r-markdown file: --- title: "Test" header-includes: - \usepackage{graphicx} output: pdf

问题 I am trying to modify the behavior of RStudio's knit button, by changing the directory to which it writes the output of knitting the Rmd file. I have started with this answer, but instead of having the filename given by a fixed string, I'd like to have the output filename based on the Rmd filename. However, the variable inputFile includes the full path to the Rmd file. Is there a way to get only the filename without the path? The header I am working with that produces the full path+filename

问题 Currently there seem to be two ways to do presentations in R: RStudio presentations, with .Rpres extension rmarkdown, with .Rmd extension To me, it looks like the latter is slightly more powerful. The input format is very similar, yet not identical. I'm thinking about converting an RStudio presentation to rmarkdown. What's the best way to do this? How about the conversion back? On that note, I'd really like to see an "in-pane" preview for rmarkdown presentations in RStudio, just like for

问题 In knitr I want to add a (small) data frame as a table using the kable package: --- output: html_document --- ```{r} knitr::kable(mtcars[1:5,1:5], format="html") ``` This returns a compact table as above, while changing it to format="markdown" returns a nice table but spanning the whole page: I have found the knitr manual but it does not cover the extra formatting options for each format. How can I change the size of a knitr table or even better, where can I get this information from? 回答1:

问题 I try to write all data analysis reports using R Markdown, because I can have a reproducible document that I can share in several output formats (Pdf, html and MS Word). However, most of my colleagues use MS Word and they have no idea about R, Markdown, etc. One advantage of using R Markdown is that I can generate my report in MS Word and directly share it with my colleagues. The disadvantage is that collaboration becomes cumbersome for me, because I receive feedback on MS Word as well

问题 I am using R Studio to create a markdown document. I tried: Jump to [Header 1](#anchor) I would like to set up a link so when a reader clicks it, can jump to a specific point on the page. Let's say the point I want them to be directed to has a header " ##Test ". 回答1: Here is a solution for HTML documents using jQuery: --- title: "Internal Links" output: html_document --- # First Section ## Second Section ### Third Section <script type="text/javascript"> // When the document is fully rendered.

问题 I'm trying to create automated PDF RMarkdown reports for fitness testing data based on the training hub city. I believe I'm very close by following the outline here: R Knitr PDF: Is there a posssibility to automatically save PDF reports (generated from .Rmd) through a loop? However, this is creating reports with the same data for only 1 hub despite both being named differently (report.MTL.pdf and report.TOR.pdf). How can I get the subgroup to loop properly to show data from the different hubs

问题 I have a fully functional interactive shiny doc using knitr/r markdwon. However, when I try to publish (deploy) it to shinyApps.io, I get an error saying the .PNG file I try to incorporate into the doc (using readPNG from the png package) is unable to open. I know the problem is related to working directories. In my original code I assigned a working directory to my folder (i.e., "C:/Users/NAME/documents/...." that contains both my .rmd file and my .png file. However, obviously my folder

问题 This is similar to how to render DT::datatables in a pdf using rmarkdown? DataTable has an option to add a pdf button and export and nice looking pdf of the Table. (see https://rstudio.github.io/DT/extensions.html) Is there a way to do this in Rmarkdown directly? It would save me effort of converting a list of DTs to kable. 来源： https://stackoverflow.com/questions/55845388/render-dtdatatables-in-a-pdf-using-rmarkdown
