title: What is R counterpart of Python comamnd requests.post()?
body: <p>A user may know R but needs to run the following python code</p>
  
  <pre><code>import requests
  import json
  
  query = "asthma"
  r = requests.post("https://ndar.nih.gov/api/search/nda_sw_removal/collection/full", query)
  
  collections = json.loads(r.text)
  collections
  </code></pre>
  
  <p>Using R libraries, how can the request.post call be rewritten in R?
  The challenge is what python does with the <code>query</code> parameter exactly.</p>
