I would expect a 4 line file, and that is indeed what I get when I try the code in question. If I append an empty line at the end of my test.txt and then apply readLines() to that file, I get [1] "abc" "def" "" "ghi" "", again as *I* would expect. What am I missing? Sorry for being a thicko.
That fifth line is more a function of the editor (RStudio) than the file. The last line ends with a newline. The editor shows this by including a blank 5th line. If the last line just stopped at the last letter, the editor would display it as a 4 line file.
