Introduction

I wrote this as an additional because I had some trouble initially starting up the Rmarkdown to WordPress process. Other people have written great guides on the process and I wanted to add some clarifyers. If you are just getting started on the process, check out other’s posts.

Initial setup

Getting RWordPress into my library

Downloading from Rstudio’s install button had an update issue, no problem. Here’s the link for the zip file. You can click your way around the setup fairly easy and get it added to your library.

library(knitr)

Issues with just copy and pasting other’s code^{obviously-but-I’m-going-to-reiterate-it}

Initially, I just copy and pasted which resulted in error codes Error in parse_block(g[-1], g[1], params.src) : duplicate label 'setup' etc. This error code comes from a duplicated chunk_name/label of the initial setup if you just open a Rmarkdown file. Give it a different name and move on.

Login information conflicts

Options

options(WordPressLogin = c('chubenn' = 'whatevermypasswordis'),
WordPressURL = 'https://chubenn.blog/xmlrpc.php')

I found that the WordPressLogin and WordPressURL have different capitalization across the blogs. Lowercase works for me.

Username

Frankly, I know it’s obvious but the username that is required is just what you registered with wordpress, not the email. Using chubenn worked while chubenn@gmail.com does not.

Website Url

First off, adding /xmlrpc to the end of the url is crucial. It’s basically a package that serves as a connection between the server and client, acting inbetween WordPress and RWordPress.
In the same obvious vein as the previous, I had previously copied the wrong URL. All you need is https://chubenn.blog.
NOT https://wordpress.com/chubenn.blog or https://wordpress.com/view/chubenn.blog.

The code for knitting to wordpress

knit2wp("whatever-the-markdown-file-is.Rmd",
title = "Ben is so cool.",
action = c("newPost"),
publish = FALSE)

A last note on editing

Peter Baumgartner and a few others have detailed lists in using the editPost function which requires a postId including other post options. This is incredibly strong because you can edit all parts of the post including categories, tags, social media releases, etc.
However, I’m finding myself checking back and forth fairly frequently between the WordPress manager and my Markdown, this is because the markdown view is way different than the wordpress viewer. In order to accomplish that, I currently am just setting the publication to false. {r publication_code echo = FALSE, eval = FALSE}.

Mabye I’ll write a revision of this post in a few months after becoming more familiar with it.

That’s basically all you need to start blogging via Rmarkdown.

So long, thanks for all the fish.^{Aslo-can-anyone-tell-me-how-to-add-indentation-to-paragraphs-in-Rmarkdown?}
