Yaml trouble at knit

[JC93OV]

Hi! I have the next error when I try to knit my Rmd to a pdf or html:

"Error in yaml::yaml.load(..., eval.expr = TRUE) : **
** Scanner error: while scanning for the next token at line 3, column 30 found character that cannot start any token at line 3, column 30
Calls: ... parse_yaml_front_matter -> yaml_load -> "

The code that give that at line 3 is my name:

1 ---
2 title: "RMarkdown"
3 author: "Juan Carlos Ortega Velasco"
4 date: "r format(Sys.Date(),"%e de %B, %Y")"

I saw a similar topic and it was solved deleting the yaml package and reinstalling it, but in my case it doesn't work.

Does anybody know what happen with yaml??

Thanks!!

Hi, thanks!

The numbers were put by me to make esier the visualization of the lines.

This is the screenshot of RStudio.

@JC93OV

date: " r format(Sys.Date(),"%e de %B, %Y") "

The issue is here. The correct syntax for this is :

---
title: "RMarkdown"
author: "Juan Carlos Ortega Velasco"
date: "`r format(Sys.Date(),'%e de %B, %Y')`"
---

• You can't use double quote inside double quote. it is either "'something'" or '"something"'
• You need to use a `r for knitr to know it is inline code

Thanks! That's it

Now, it works. I'll take a look to the Cookbook!
