title: List of list to dataframe
body: <p>I obtain from an endpoint in an API query a list of 370 lists of 19 elements each. I am trying to convert this into 370 rows with 19 columns in R.</p>
  
  <p>When I try as.dataframe, I get an error message : arguments imply differing number of rows: 1, 0
  When I try lapply(datos, ldply), I get the following error :  Results must be all atomic, or all data frames</p>
  
  <p>Also tried the flatten list post. but also get the message: arguments imply differing number of rows: 1, 0</p>
  
  <p>PS: I checked previous similar questions on the subject, tried the answer, but I didn't get what I wanted</p>
