title: How to check grammar in RStudio?
body: <p>OK, my first question.</p>
  
  <p>I have to write my homework in RStudio and I am using Rmarkdown to have a nice output. My mother's tongue is not English, so I have some trouble with grammar sometimes. Spelling check is working well (just hit F/ and let it go through), but I don't find something for grammar. Is there a way to bring software like Grammarly and similar into RStudio? I googled and I didn#t found something. I would prefer an open-source grammar checker.</p>
  
  <p>A few examples:</p>
  
  <p>He walk to School.</p>
  
  <p>I Know RStudio is cool.</p>
  
  <p>Coefficient can be tricky to be interpret.</p>
  
  <p>I know that in first sentence walk must be converted to walks.</p>
  
  <p>In second sentence Know must be written as know.</p>
  
  <p>In the third sentence, Coefficient needs a The in the beginning and must be written lowercase.</p>
  
  <p>In websites like this, I am writing with Grammarly.</p>
