title: Converting integer list object to double list object without changing the structure of the list object
body: <p>Here is how my data look like.<a href="https://i.stack.imgur.com/mz3yM.png" rel="nofollow noreferrer">My initial dataset</a></p>
  <p>I want to convert the objects that have integer characteristics to double. When I am using as.double or lapply(mydataset, as.numeric) the list objects are changed to double[25] as shown in the picture.<a href="https://i.stack.imgur.com/Km1LL.png" rel="nofollow noreferrer">MY dataset after converting to double</a>.</p>
  <p>My question is how I can convert the integer object to double keeping the structure of each object 5*5.</p>
