Perhaps this would be more instructive (after adding back the missing parentheses):

sigma=2; for( z in -:1 ){
 print( substitute(paste(z,sigma)) )
print( paste(z,sigma) )
print( substitute(paste(z,"sigma")) )
print( paste(z,"sigma") ) ; cat("\n")}

I don't know if `substitute` is so much superfluous as incompletely called. I would have thought the code might be:

   substitute( paste(z, sigma), list=(z=z) ) # puts value of z into the expression

Or perhaps:

substitute( z == sigma, list=(z=z) )

Or:

bquote( .(z) == sigma) 

Assuming the goal were to label a plot with the value of z in a plot at a particular location. The relevant help pages are:

?expression
?substitute
?bquote
?plotmath
?text

Best;
David.
