knit2wp function does not pick up categories and publish options

[rpodcast]

I wanted to use the new knit2wp function to create a post in the drafts section of my Wordpress site at r-podcast.org which is a self-hosted blog. While the function successfully made a post, it automatically posted it instead of putting it in draft form and was uncategorized, see post here. The R markdown file was simply the RStudio R markdown default template (with modifications to put the images in my Dropbox according to Yihui's demo here and here's the code I used to compile:

library(RWordPress)
library(knitr)
knit2wp(input='test_wp.Rmd', title = 'Test from knitr to wordpress',
    categories = c('Articles'), publish=FALSE)

Contents of the file can be seen in this gist in case it helps to debug.

Sorry I have no idea on why categories does not work. I just tested it and I can reproduce the problem. I think this might be a problem of RWordPress.

For publish=FALSE, it is not an argument of knit2wp(). I can add it if you want.

Thanks, Yihui! For my purposes, having the publish argument added would be sufficient enough, as I can easily assign the category in Wordpress itself when it's ready to be published.

[yihui]

Great. The publish argument has been added. Thanks!

Hi Yihui, Great work on knitr and related packages. I have found them indispensable. I know this query has been closed but I just wanted to let you know I have found a weird solution. Categories works if you set more than one category :) One category does nothing but adding an additional arbitrary category seems to make it work perfectly.

@joedemby Thanks for sharing your solution! That sounds like a bug of the RWordPress package.

Anyway, perhaps you have heard about it -- I spent a whole year last year working on a new package specifically for building websites with R Markdown: https://github.com/rstudio/blogdown

No problem. Just found it by accident. Thanks for the referral of blowdown. I shall look at it right away. :)
