Error in -title : invalid argument to unary operator

[jorondo]

Rmarkdown suddenly started giving the following errors when compiling.

> 
> > ---
> + title: "Untitled"
> Error in -title : invalid argument to unary operator
> > author: "ronj2303"
> Error: object 'author' not found
> > date: "6 2 2021"
> Error in date:"6 2 2021" : NA/NaN argument
> In addition: Warning message:
> NAs introduced by coercion 
> > output: html_document
> Error: object 'output' not found
> > ---
> +

This is from compiling the first 6 lines of code that appear when you start a new .rmd document:

---
title: "Untitled"
author: "ronj2303"
date: "6 2 2021"
output: html_document
---

Weirdly, knitting works flawlessly. I have tried rebooting Rstudio, updating the markdown package, to no avail; the default .rmd template is riddled with these errors (and my markdown scripts as well).

I'm quite new to markdown and R in general.
I am posting here because google searches did not yield any solution regarding these errors.

Thanks in advance!

So you means this works when you are trying to knit the document (using the Knit button in RStudio IDE I presume?)

When exactly does the issue you described happens ?

It seems you sent tha YAML header to console.

Yeah that was indeed a rookie mistake. I was trying to run the whole code through the console. Sorry about that, thanks for the link!

No worries!

If your question's been answered (even by you!), would you mind choosing a solution? It helps other people see which questions still need help, or find solutions if they have similar problems. Here’s how to do it:

FAQ: How do I mark a solution?

If your question has been answered, don't forget to mark the solution! How do I mark a solution? Find the reply you want to mark as the solution and look for the row of small gray icons at the bottom of that reply. Click the one that looks like a box with a checkmark in it: [image] Hovering over the mark solution button shows the label, "Select if this reply solves the problem". If you don't see the mark solution button, try clicking the three dots button ( ••• ) to expand the full set of options. When a solution is chosen, the icon turns green and the hover label changes to: "Unselect if this reply no longer solves the problem". Success! [solution_reply_author] …

Will do, good to know. Cheers!
