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!

Tao
[1] "N.C.?"
[1] FALSE
[1] "?"

Use 'charToRaw' to see what the bytes making up the string are:
[1] 4e 2e 43 2e 20

Probably a non-breaking or other special space. You can try utf8ToInt
on your character string to convert it to UTF-8 codes. Then look up
the character by its code.

HTH,

In the sample you provide it is HEX 20 which is ASCII for "space."  So
either, it really is a space, or it didn't copy in your message.  I
would suggest copying the string and pasting into a hex editor. 

Doing that with the "N.C. " from your message yields:

22 4E 2E 43 2E 20 22

The "20" is the ASCII "space" character.  Just possibly, if you are
using a file saved in a unicode format, it could be a "no-break space"
- Unicode point U+00A0, or UTF-8 "c2 a0".  Good luck.
