Hi list, I've encounter this problem (see below). I know it's particularly R-related and it's easy to get by but it still bothers me a lot.
It looks the last character of "N.C. " is a space to me, but it's clearly not. Can someone tell me a way to figure out what character is in the last position. Thanks!
