Subject: position of the end of a text file
Hi!
I need to find the position of the last character (could be empty
space) of a vector of text files (my.text.vector) that I have read
into R. I tried Google, but all I have found needs a pattern.
I tried the following
as.integer(regexpr("??", my.text.vector)
but it returns 1 or even the correct number, but not consistently. I
understand that ?? is an operator, thus should not be used but itself.
Any ideas?
Thanks,
Henri-Paul
