r-markdown

问题 I used to be able to include images from URLs in PDF reports generated from shiny apps doing  . A few markdown versions later I get the following error: ! Unable to load picture or PDF file https://i0.wp.com/wptavern.com/wp-content/uploads/2016/07/stack-overflow.png?ssl=1 for the same code.

问题 I'm editing an R markdown file (.Rmd) that has a lot of R code blocks to move groups of those code blocks into "child" documents to simplify rearranging sections (if nothing else). As I convert sections to child documents, I would like to test the new child document without running the rest of the blocks and other children. However, when I use to comment out those sections, the R blocks still run (but RStudio makes the sections "look" as though they were commented out). If I eliminate the

问题 I have a package with a README.Rmd that I pass to rmarkdown::render() producing README.md and a directory README_files , which contains images in README.md . This looks like the tree below. README_files is not a standard package directory, so if it isn't in .Rbuildignore , checking the package with R CMD check shows a note: * checking top-level files ... NOTE Non-standard file/directory found at top level: README_files But including the directory in .Rbuildignore leads to a warning, if and

问题 The bookdown offers great cross-referencing options for equations, figures, tables and sections: https://bookdown.org/yihui/bookdown/cross-references.html However, they seems to not work when I set as an output 'rticles::elsevier_article'. What are the available options for cross-referencing in rticles? 回答1: I haven't tried, but there is a possible solution here: https://bookdown.org/yihui/bookdown/a-single-document.html Particularly, specify in your YAML metadata: output: bookdown::pdf_book:

问题 When preparing a presentation with RMarkdown's ioslides, I encountered a problem which I have not been able to find a solution for. This answer did also not solve this specific problem. Sometimes, two-column layouts are best to explain something with an image on one side and text on the other. However, As in the following example, the column breaks do not appear to work as desired.
