knitr

问题 I use RMarkdown and knitr for dynamic report generation. When knitting a document, I would like to have the code from an Rmarkdown chunk included in the knitted document and run the code -- but not show the output. That is, I would like to be able to do what this code suggests: eval=TRUE, echo=TRUE, include=FALSE ... and make knitr run the code ( eval = TRUE ), show the code ( echo = TRUE ), but not show the lengthy output (attempted with include = FALSE ), but my attempts fail.

问题 Is it possible to change the line spacing for the abstract specified in my YAML header to single space, while leaving the rest of the document in double space? My YAML is below: output: pdf_document number_sections: true title: | | My Title author: - Me header-includes: - \usepackage{setspace}\doublespacing - \usepackage{float} abstract: "My abstract" keywords: "My keywords" date: "`r format(Sys.time(), '%B %d, %Y')`" geometry: margin=1in fontsize: 12pt spacing: double fig_caption: yes indent

问题 I`m aware how to use additional Latex-packages for pdf-format output from .Rmd files using --- header-includes: - \usepackage{mathtools} --- in the YAML header. However, this does (of course) not work if one specifies output: html_document . --- output: html_document header-includes: - \usepackage{mathtools} --- Using additional Latex-Packages could be of interest for output: html_document , too - especially in math expressions (MWE below) --- title: "MWE" output: html_document header

How do I achieve this? 回答1: This should work for you: ```{r cars, echo=FALSE, results='asis'} myCondition <- TRUE if(myCondition) { cat("##

问题 I am playing with Tal's intro to producing word tables with as little overhead as possible in real world situations. (Please see for reproducible examples there - Thanks, Tal!) In real application, tables are to wide to print them on a portrait-oriented page, but you might not want to split them. Sorry if I have overlooked this in the pandoc or pander documentation, but how do I control page orientation (portrait/landscape) when writing from R to a Word .docx file? I maybe should add tat I

问题 I have this html knit output from Rmarkdown but since it is pretty heavy (it is an online guide), the page takes too long to show up when opening the link. I tried to divide the rmd file into distinct rms sub files as below shown but I still can't get the result.
