Reading the last n lines from a huge text file

I have created a connection to a file using

con=file(path_of_myfile)

Now I want to read only the last line without loading everything (it is a HUGE file).

I am trying to use

?readLines

with no success.

Any idea?

Since you are on Windows, download and install Duncan’s Rtools which you would need anyways if you wanted to build R packages yourself. (If you were on Linux then the only difference is that you would not need to download anything since gawk is already there.) Then issue this R command:

system("gawk 'END {print}' myfile", intern = TRUE)
