[R] Supperscript, subscript and double lines in the main/sub title and using greek letters
Dear R-help,
I am trying to express myself as best as I can here. If you also use Latex
to edit math reports or other languages with similar editing method,
you'll see what I'm talking about. My sincere appologies if my question
is
not clear enough to some extend, as also I'm not able to provide my code
here because I don`t know which one I can use...
When editing the title in R plots, such as using 'plot', or
'xyplot' in
'lattic', what method do you use to write greek letters and make use of
superscript and subscript, e.g. to write mathematical expressions like
using Latex:
\sigma^2
\tau^{2s}
\mu_i
\pi_{2s}
Also I would like to learn how to make two lines in the main title or sub
title if the text I need it too long for putting in a single line, e.g. are
there some R code/syntax allowing me to do something like in Latex to make
two lines in the title, for example using '//' or '\\' to
seperate the two
parts of the text I want to put in two lines??
I heard about using something like
plot(x,y, main=expression(....))
but from neither '?plot' or '?expression' could I find
comprehensive
information about what I need...
Many thanks!

And a "*" seems not > required when a greek letter is needed outside the double quotations, e.g. >when applying just 'expression(...)'. Again, a "*" is needed when making subscript as shown above... It seems "~" is reserved for making spaces before/between greek letters. What if we need "~" in the title as "~" is a standard notation in statistics when expressing "is from" when writing down a distribution, e.g. 'X~N(0,1)'...
