Hello,

You can obtain the special character plus/minus by a copy from the MS Windows
"Character Table" and paste it in the R console or in your text editor
as (NotePad or Emacs). Then, you can use it in your script:
x <- 5
y <- 0.25
paste (x, "±", y)

Cheers

François Michonneau

Another way that works on my Windows XP system is
to use "\261" .

Please note Windows escape codes are not portable thus not recommended as Martin
