It appears in the topic shown by ?Special, "Special Functions of 
Mathematics," but only in the LaTeX version.  You can see that in the 
PDF version of the Reference Manual, or (if you have things set up 
correctly), by saying

options(help_type="pdf")
?Special

I don't know of any examples where someone has shown an integral sign in 
text or html versions.  It's not a symbol supported by the R help 
system, it would depend on hand coding the right thing.
