Actually, quick correction here. That should be:

  NewListObject <- dget("YourTextFile")

dget() will enable simple assignment of the textual input, whereas
source() will just evaluate it and assignment with source() creates a
list object, unless you use:
  NewListObject <- source("YourTextFile")$value
