r-markdown

问题 I'm trying to run a Rmarkdown file ( myfile.Rmd ) from the command line terminal. This file needs to take an argument to work. We can use this simple file as an example: --- title: "Simple example" output: pdf_document: default --- ```{r read_arg, include=FALSE} args = commandArgs(TRUE) VAR = args[1] ``` ```{r show_var} VAR ``` So, first of all, is it possible to run a Rmarkdown file by reading arguments as done for Rscripts? I mean, not by reading input files as described in this question.

问题 in markdown, my_stock_index is my stock index. But I want it to show my_stock_index . How can do that? 回答1: You just escape it with a backslash: my\_stock\_ticker is what you type to get my_stock_ticker The syntax seems to work for all markdown parsers. However, php markdown parsers use the numeric character reference _ instead of the actual character in it's output. 回答2: The single backslash escape works fine in Jupyter unless you are in an italicized block, in which case, you want to close

问题 I have a rmarkdown file which I need to knitr to get an html output composed of three different pages. Each page has some chapters (1 chapter in the first, 4 in the second page and 4 in the third). I need to repeat the full TOC ( with all chapters within ) in each page. With the code I have each TOC is split and refers to chapters of the single page only. I copied following code at the beginning of each page. I am very new to this thank you so much. --- title: "page" author: "me" date: "26/02

问题 What I want: I'd like to have German quotation marks in my TeX-PDF via rmarkdown and tinytex on MacOS (Catalina). See for example: The problem: It used to work following the guidelines as proposed here. But now, it stopped working. I only get English quotation marks, but not German ones: What I tried, without success : I updated my R packages I updated TeX packages I checked that the TeX package "csquotes" is installed I changed the language from "de" to "de-De" R-Code : --- title: "German
