How can I type the R which indicates real or the C that indicates integers?
I want to the same with numbers and type a 1 with a vertical bar. How can I do this?
Hello,
Wrap the letter with \mathbb{}
Note that this works with capital letters only :
$\displaystyle \mathbb{ABCD}\mathbb{EFGHIJKLMNOPQRSTUVWXYZ}$
For the 1, I bet you want to use it for the indicator function... I don't think there is a simple command with it. But use \bold{1} (bolded) and we'll understand you
http://www.statslab.cam.ac.uk/~elie/ext/tex/ look "Example Code with Overlaps". But I cannot open the file due to problems of mine.
