R help - Aug 2017 - bquote question

Dear All,

could you please provide input on the following:

plot(1:10,main=paste("\n   ","\nABCD","\n   
","\n    ","\n    "),cex.main=1.3)

a<-500 
b<-12 
mtext(bquote(bold(.(formatC(1.2*a,decimal.mark=",",digits=2,format="f")))~
" words "~bold(.(b))~" words"~"\n    "~"\n   
"))



as you will see form the sub-title only the result of 
formatC(1.2*a,decimal.mark=",",digits=2,format="f") gets
bolded, while the part bold(.(b)) does not seem to bold the letter
'b'... In addition, the spacing ("\n ") at the end of the
mtext line also does not seem to get recognized.... any thoughts on what I may
be doing wrong?

much appreciate your help...

Failing to read the ?plotmath page. Numeric values do not get bolded. You will
need to wrap with as.character(). And "\n"'s are not recognized.
