Occasionally, when I use the
readLines() functions I get the following warning message:
readLines("XXX") : incomplete final line found on 'XXX'
To fix this warning message is straight forward, just add a newline at the end of the file.
My questions are:
- Why is this an issue?
- What are the (historical?) reasons behind this warning?
- Is it good practice to promote this warning to an error?
Note: RStudio has an option that automatically adds a line breaks: Code -> Saving
