问题 Similar to how to create a loop that includes both a code chunk and text with knitr in R i try to get text and a Code snippet created by a Loop. Something along this: --- title: Sample output: html_document params: test_data: list("x <- 2", "x <- 4") --- for(nr in 1:3){ cat(paste0("## Heading ", nr)) ```{r, results='asis', eval = FALSE, echo = TRUE} params$test_data[[nr]] ``` } Expected Output would be: What i tried: I tried to follow: https://stackoverflow.com/a/36381976/8538074. But

问题 Say I have a simple rmarkdown document called test.Rmd --- output: pdf_document --- This code tries to save output to a file called 'example.txt' ```{r} sink(file='example.txt') sink.number() library(MASS) summary(cars) sink() sink.number() ``` If I run this in RStudio (using the knit PDF button) then I get lots of output but I believe the most important is the following (I can include the other output on request) processing file: test.Rmd "C:/Program Files/RStudio/bin/pandoc/pandoc" +RTS

问题 Can someone please provide a working example of how to use set.seed() globally in R Markdown? I am aware of Yihui's documentation based on this bug report, but I get an error message when I put the suggested option in my setup chunk as knitr::opts_chunk$set(cache.extra = rand_seed) . What am I missing? I currently just have a random seed in the first code chunk that needs it, but later chunks should use the same seed. [UPDATE BELOW] My setup chunk: ```{r setup, include=FALSE} #knitr::opts
