Error in RMarkdown knit yaml

rmarkdown
yaml
#1

I tried knitting my old projects in rmarkdown but I keep getting this error:

Error in yaml::yaml.load(..., eval.expr = TRUE) : unused argument (eval.expr = TRUE) Calls: <Anonymous> ... parse_yaml_front_matter -> yaml_load -> <Anonymous> Execution halted

These proejcts used to knit before so I don't understand what is the problem now.

Thank you so much,

R Markdown cannot Knit HTML; YAML Error
#2

Could you share a small reproducible example of your issue? We can't actually help you with out knowing the content of the YAML header in your .Rmd file

Trying adding this into the top of your r markdown file:


library(knitr)
#library(ggplot2)
knitr::opts_chunk$set(echo = FALSE)
knitr::opts_knit$set(root.dir= normalizePath('..'))
knitr::opts_chunk$set(error = FALSE)

I would do as recommend by @andresrcs. create reprex of your issue. One thing you can try is have the code on the top in an R chunck

Try adding an empty line between the YAML header and the <style> tag and indenting your YAML this way

output: 
    html_document

Again hard to help you any further without a reproducible example (BTW a screen capture is not a reproducible example and is not a good thing to do here)

I am a new user so i am having a bit of hard time with this, I tried adding the space before style still no result and I tried adding my codes but then I got an error that new users are only allowed to use 2 links so i wasn't sure what to do?

Use four backticks and the "markdown" syntax hint to surround the source of R Markdown documents:

Type this:

````markdown
---
title: "It's full of cars!"
output: html_document
---

```{r setup, include=FALSE}
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.

```{r cars}
summary(cars)
```
````

See this:

---
title: "It's full of cars!"
output: html_document
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

## Outline

This assignment requires you to read the following notes.  The first two notes are just for your general knowledge.  The last one contains a paper, and the assignment requires you to replicate the main findings of this paper.

  1. [Note 1](http://econ.lse.ac.uk/staff/spischke/ec524/evaluation1_07.pdf) - Evaluation and Randomization
  2. [Note 2](http://econ.lse.ac.uk/staff/spischke/ec524/evaluation2_07.pdf) - Evaluation and Regression
  3. [paper](https://www150.statcan.gc.ca/n1/en/pub/11f0019m/11f0019m1998126-eng.pdf?st=IIGv0ZAG) - Do computers make workers more productive.

## Details

In order to replicate the results from the paper, you need to go to the york data library and download the data set called "General Social Survey, Cycle 9, 1994 [Canada]: Education, Work and Retirement" from ODESI. [Start here](http://researchguides.library.yorku.ca/c.php?g=679400&p=4789750).

You can download the data in any format you want. I normally download the data in STATA format, and use the "haven" package to load it into R.  The paper contains an appendix with the details of their data construction.  To get you started, I providd some code below to calculate hourly wages.  The rest is up to you.

The Main table to replicate is Table 4.

Once you replicate the table, you will:

  1. Submit your table and code via an html document produced in R markdown.
  2. Provide a very brief write-up of your results in the context of the language used in Note 2, linked above.  In particular, pay close attention to the section on "falsification."  Can you relate this discussion to the output in the table?

The following 3 tables are testing the effect of computer or fax, along with other variables on the natural log of hourly wages:

```{r,echo=FALSE, results="asis"}
stargazer(m_n_cmpt, m_y_cmpt,f_n_cmpt, f_y_cmpt,

          column.labels = c("Men No Occ", "Men Yes Occ", "Women No Occ", "Women Yes Occ"),
          keep = c("cmpt"),
          omit.stat=c("LL","ser","f","rsq"),
          report = "vc*t",
          type="html"
          )

stargazer(m_n_fax, m_y_fax,f_n_fax, f_y_fax,
          title="Table 2: Tools Entered Seperatly Fax",
          column.labels = c("Men No Occ", "Men Yes Occ", "Women No Occ", "Women Yes Occ"),
          keep = c("fax"),
          omit.stat=c("LL","ser","f","rsq"),
          report = "vc*t",
          type="html"
          )


stargazer(m_n_cf, m_y_cf,f_n_cf, f_y_cf,
          title="Table 3: Tools Entered Together",
          column.labels = c("Men No Occ", "Men Yes Occ", "Women No Occ", "Women Yes Occ"),
          keep = c("cmpt","fax"),
          omit.stat=c("LL","ser","f","rsq"),
          report = "vc*t",
          type="html")
```

In Table 1, we have a dummy variable that takes the value 1 if the worker uses a computer and takes the value 0 otherwise. The wage premium for male computer users equals 19% (i.e. exp(0.175)-1) and it is equal to 19% (exp(0.171)-1) for women. The wage premium for men dropped to 12% when we include the occupation variables and the wage premium for women users dropped to 14% when we include the occupation variables. 


In Table 2, we replaced the computer use dummy variable by a fax user dummy variable. When this is done, we find a wage premium of 19% for male fax users and 24% for female fax users. When we add the 33 occupation variables the wage premium for male fax users drop to 12% and the women users dropped to 17%. 

In Table 3, we entered both fax users and computer users.  The wage premium for computer users is 14% for men and it is 11% for women.  On the other hand, the wage premium for fax users is 15% for men and it is 20% for women.  Adding occupation variables, it dropped the computer users to 9% for men and 10% for women. The men fax users dropped to 10% and the women fax users dropped to 15%.

From the robustness test we can see that all of our variables are still significant, so we can’t discuss anything regarding falsification since everything looks the same significance.

Have you updated Rstudio recently? try uninstalling and re installing yaml package

remove.packages("yaml")

Restart R session with Ctrl + Shift + F10

install.packages("yaml")

Also, your example is not actually reproducible since we dont have access to this file.

omggggg removing yaml and installing it fixed the problem, thank you very much, you are a life savor!!!
I have been trying to solve this issue since yesterday and there wasn't anything similar to it on google!

I really apprecite your help :smile:
