How to create a R markdown file and append a string variable to the R Markdown document

Question

I am running a shiny application from which I want to create a R markdown file and append a string of characters to the R Markdown document

Answer 1

rmd_content <- paste0("```Your R markdown string content",string_variable,"```")

rcon <- file("markdown_file.Rmd", "w") # Create Rmarkdown file
cat(rmd_content, file = rcon) # Write your content to Rmarkdown file
close(rcon)

在此 R 代碼之后，您應該在當前工作目錄中有一個名為“markdown_file.Rmd”的文件
