r-markdown

问题 In R, I have character objects that contain LaTeX macro definitions. The challenge is to use these objects in R Markdown documents, so that the macro definitions are rendered correctly when the .Rmd files are converted to LaTeX (and then to PDF). It is a challenge because Pandoc (v2.9.1 and 2.9.2) fails to render some macro-generating code correctly, even when that code is valid LaTeX. Here is a minimal example. First, consider this Rmd file: --- title: "Rendering LaTeX Macros from R Objects"

问题 I just bought a new Mac. I've cloned my git repo onto it, and ran the following, which worked fine on the old Mac: rmarkdown::render(input = "statement.Rmd", output_format="pdf_document", output_file = paste(Payees$Payee[i], "identifying text", i, "2018_02", ".pdf", sep=''), output_dir = "~/Desktop/path/to/directory") I've installed tinytex on the new box, and I've run install_tinytex() . Here's the error I get: tlmgr: package repository http://ctan.math.washington.edu/tex-archive/systems

问题 The example below (i.e. saved as a file index.rmd ) has the same code chunk to display an image above and below the top level heading, but the image doesn't appear above the top level heading. This occurs if there is a file _output.yml with only this entry bookdown::gitbook: in the same directory. That line seems to enforce a table of contents (which I want) and that appears to strip out anything (image or text) before the first top level heading by default (which I don't want) - so can this

问题 Background: I am featuring a blog built on @YihuiXie's R package blogdown . Problem: When I render_site() , all source files (*.Rmd) are rendered - even the unchanged source files are re-reendered. This complete re-rendering is time consuming and unnecessary (I think). Question/ Desired Solution: How can I prevent blogdown from re-rendering the unchanged source files? I want blogdown to render only new or changed source files. What I have already tried: I've read the blogdown book; Yihui

问题 This question already has an answer here : How should I deal with “'someFunction' is not an exported object from 'namespace:somePackage'” error? (1 answer) Closed 14 days ago . I have this Error when I first time using R Markdown, just a simple test run. --- title: "test" author: "Lulu" date: "3/6/2018" output: html_document --- ```{r} library(datasets) data("airquality") summary(airquality) ``` then it reports: output file: test.knit.md Error: 'is_latex_output' is not an exported object from

问题 Documentation for Bootswatch suggests I can use a dropdown menu from a tab in a tabset: How can I achieve this with Rmarkdown? I've tried: # SECTION 1 {.tabset .tabset-fade} ## Section 1.1 ## Section 1.2 {????something here?????} ### Section 1.2.1 <<<<<<<<< want this to appear under the dropdown menu 回答1: This is now available within the development version of rmarkdown , which you can install this via devtools::install_github("rstudio/rmarkdown") . To add a dropdown menu, you must add

问题 This is a follow up to an earlier question I asked here: creating accompanying slides for bookdown project Bookdown allows compiling the file to various format, including multiple pdf . The issue is therefore to give the output different names. If not, the second pdf compile overwrites the first one! In the comments to my earlier question, I wrote: "I just need to understand how to change the file name - because bookdown::pdf_book and bookdown::pdf_document2 output to the same file - which
