title: Creating quantiles
body: <p>I have a data set of individuals with their socioeconomic scores, ranging from -6.3 to 3.5. Now I want to assign each individual to their quantiles based on their socioeconomic score.</p>
  
  <p>I have a dataset named <code>Healthdata</code> with two columns: <code>Healthdata$SSE</code>, and <code>Healthdata$ID</code>.</p>
  
  <p>Eventually, I would like to get a data frame matched by their SSE quantiles.</p>
  
  <p>How can I do this in R?</p>
