Stargazer output in RMarkdown - What is my illegal charachter?

Question

I am running logistic regression models and try to print out the output with stargazer in RMarkdown. I have applied dcolumn in my setup, but I still get "! LaTeX Error: Illegal character in array arg." when I try to knit the document to a pdf. I have tried to just copy in the LateX-code, but it also says I have an illegal character. Could someone help me to find the illegal character?

RMarkdown file:

title: "Tables and Figures"
author: "me"
date: "November 2019"
header_includes: - \usepackage{dcolumn}
output: pdf_documentclassoption: landscape




 ```   
 {r Regression results Q21 1, results='asis', echo=FALSE}

 Q21e_teaching99 <- glm(Q21e_teaching ~ Country + Field + typeposition + Gender + Age, data = 
 SurveyPHEC, family = binomial(link = "probit"))

 stargazer(Q21e_teaching99,  type="latex", align = TRUE)

 ```

LatexCode that this produces:

! LaTeX Error: Illegal character in array arg.

Can you show the complete .tex and .log files? If I guess a couple of packages, I can compile your code fragment — samcarter_is_at_topanswers.xyz, Dec 02 '19 at 14:25
The header looks fishy. maybe a couple of linebreaks would be in order? — samcarter_is_at_topanswers.xyz, Dec 02 '19 at 14:29
Thank you for the response. By headers, do you refer to "length of NULL cannot be changedlength of NULL cannot be changedlength of NULL cannot be changedlength of NULL cannot be changedlength of NULL cannot be changed"? — Ingvild Reymert, Dec 02 '19 at 14:42
With headers I mean the stuff like `output: pdf_documentclassoption: landscape` — samcarter_is_at_topanswers.xyz, Dec 02 '19 at 14:46
Ah, that is why I have some huge tables and have set the header to produce the pdf in landscape format. — Ingvild Reymert, Dec 02 '19 at 14:53
"output: pdf_documentclassoption: landscape" is just written so I get the pdf in landscape format — Ingvild Reymert, Dec 02 '19 at 14:58
I understand *why* you want to write that, but I don't think the syntax is correct. At the very least a linebreak is missing — samcarter_is_at_topanswers.xyz, Dec 02 '19 at 14:59

The error indicates that the dcolumn package is not loaded. The reason it is not loaded are multiple syntax errors in your yaml header.

The following header should load the package (note the added line breaks):

---
title: "Tables and Figures"
author: "me"
date: "November 2019"
output:
  pdf_document:
    keep_tex: true
header-includes:
   - \usepackage{dcolumn}    
classoption: landscape
---
