title: R - Loop to import trimestral survey data to a single data frame to see evolution of variables
body: <p>I'm new to R programming. I have a function that imports trimestral data on a survey from a website to work with in R. The function from the package <code>eph</code> is as follows: </p>
  
  <pre><code>get_microdata(year = 2019, trimester = 2 , type = "individual")
  </code></pre>
  
  <p>I need to create a loop to import the corresponding data from year 2012 on for each trimester to a single data frame so as to be able to see the evolution of the individual variables throughout time. </p>
