将markdown转换为R中的json

Question

Here are the steps I would like to execute:

1. Read a markdown file (see below) into R
2. Convert the markdown text to JSON
3. Send the JSON in an API POST call

Eg. markdown text file:

## This is a list

+ one
+ two
+ three

#### Do a thing
```coffee
points <- rnorm(10)
plot(points)
```

#### Do something else

Steps 1 and 3 are easy, but step 2 is the one I don't get. A call to rjson::toJSON or RJSONIO::toJSON doesn't format the output JSON correctly. Does anyone know of a way to do this. This README on github has an example of what seems like a nice markdown to JSON conversion.

Answer 1

rCharts has a couple of utility functions that can do this easily. I am assuming your Rmd file is saved as test.Rmd . You can view the published gist here

require(rCharts)
payload = create_gist('test.Rmd', description = 'Testing Md to Gist')
post_gist(payload, viewer = 'http://gist.github.com/')

Is this what you were looking for?

UPDATE: If you want to update the gist you created, you can use the update_gist function, and pass it the gist id.

update_gist(payload, id, viewer = 'http://gist.github.com/')

You can use options(github.username = ..., github.password = ...) if you don't want to enter your username and password in your R console.
