First name and last name inverted in bibliography r markdown - r

Question

I got a problem using R-markdown to write my master's work. I am using the papaja package. Everything's fine except that when I knit my document to produce a pdf the first name of the author in my bibliography are BEFORE the last name. Here is a little reproducible example of my problem. Here is the r-makrdown content:
---
title: "The title"
shorttitle: "Title"
author:
- name: First Author
affiliation: 1
corresponding: yes # Define only one corresponding author
address: Postal address
email: my#email.com
- name: Ernst-August Doelle
affiliation: "1,2"
affiliation:
- id: 1
institution: Wilhelm-Wundt-University
- id: 2
institution: Konstanz Business School
abstract: |
Enter abstract here (note the indentation, if you start a new paragraph).
note: |
Complete departmental affiliations for each author (note the indentation, if you start a new paragraph).
Enter author note here.
keywords: "keywords"
wordcount: X
class: man
lang: american
figsintext: yes
lineno: yes
bibliography:
- r-references.bib
output: papaja::apa6_pdf
---
```{r message = FALSE, warning = FALSE}
library("papaja")
apa_prepare_doc() # Prepare document for rendering
```
[#R-papaja]
# References
```{r create_r-references}
r_refs(file = "test-references.bib")
```
\setlength{\parindent}{-0.5in}
\setlength{\leftskip}{0.5in}
\setlength{\parskip}{8pt}
And here are my references which are in the "test-references.bib" file:

#Manual{R-base,
title = {R: A Language and Environment for Statistical Computing},
author = {{R Core Team}},
organization = {R Foundation for Statistical Computing},
address = {Vienna, Austria},
year = {2015},
url = {https://www.R-project.org/},
}
#Manual{R-papaja,
author = {Frederik Aust and Marius Barth},
title = {papaja: Create APA manuscripts with RMarkdown},
year = {2015},
note = {R package version 0.1.0.9054},
url = {https://github.com/crsh/papaja},
}
The output in the pdf for the reference is:
Frederik Aust and Marius Barth.papaja: Create APA manuscripts with RMarkdown, 2015.20URL https://github.com/crsh/papaja. R package version 0.1.0.9054.
And I expect:
Aust Frederik and Barth Marius .papaja: Create APA manuscripts with RMarkdown, 2015.20URL https://github.com/crsh/papaja. R package version 0.1.0.9054.

Answer 1

Your paper was probably already due... Anyway. You should have the authors in the format Lastname, Firstname [and Lastname, Firstname]*.
In your case:
#Manual{R-papaja,
author = {Aust, Frederik and Barth, Marius},
title = {papaja: Create APA manuscripts with RMarkdown},
year = {2015},
note = {R package version 0.1.0.9054},
url = {https://github.com/crsh/papaja},
}
