When I tried to use knit error message:
[WARNING] This document format requires a nonempty element.
Defaulting to 'nelu.knit' as the title.
To specify a title, use 'title' in metadata or --metadata title="...".

Output created: nelu.html

Try to create a simple Rmd file that you can knit to Word.

The easiest way to do that is with File in the RStudio menu:
File | New File | R Markdown... and then select the Word button and click OK .
An .Rmd-file is then generated for you (but not yet saved).
So save it with an .Rmd extension and click the knitr button.

On my computer it produces a .docx files that is immediately opened by Word.
I think it depends on the settings of your computer if Word opens the file automatically or not.

Anyway: the first lines of the .Rmd file shows the 'YAML' lines that are necessary to let knitr do its work:

---
title: "Untitled"
author: "My name"
date: "2022-08-31"
output: word_document
---

Your warnings suggest that there is something wrong with the YAML lines that you have used.

Yes this warning means that somehow your document is missing a title: or have a title: that cause an issue. Can you share more about the content ?

I am starting new Rmarkdown file like these:

title: "Untitled"
author: "Nelu"
date: "September 10, 2022"
output: word_document

knitr::opts_chunk$set(echo = TRUE)

R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.

When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

summary(cars)

Including Plots

You can also embed plots, for example:

plot(pressure)

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.

Your header looks good, but it is essential that this header is started and ended with ---.

Can you format your code correctly so that we can check that the Rmd file is ok ?

FAQ: How to Format R Markdown Source

Also can you share the results of rmarkdown::pandoc_version() ?

Thank you !

It is normal code when start new rmatkdown file

9

It is still good practice to format your code correctly.

Can you share the result of rmarkdown::yaml_front_matter run on your input file ?

Also what are your tools versions ?

I can't reproduce using default template document with latest version of tools.

I instaled Rstudio from Anaconda

You keep posting the same error message, but that don't help us to help you.

I don't use RStudio from anaconda. Useful information:

  • Which version of RStudio it is ? Is it the latest ?
  • Which version of Pandoc is used ? rmarkdown::pandoc_version()
  • Which version of rmarkdown is used ? Did you update to latest ?

With issue like that we can't reproduce, it is sometimes related to the user environment. Please to update the tools. I don't know how Anaconda maintain the software, but if you can use R and R Studio outside of anaconda, especially if they don't have latest version that may fix things
