R help - Jul 2006 - main= bquote(paste("Results for ", beta, "3", ==.(b1)))) doesn't work.

Hi,

I need to plot the beta as the symbol, followed by the index 3 as the title of a
graph.

This code works> main= bquote(paste("Results for ", beta ==.(b1)) 

but I also need the index 3.
I tried (simplified):
>plot(x,y, main= bquote(paste("Results for ", beta, "3",
==.(b1))))
and a few other versions, but I can not get it to run properly.

Any help would be greatly appreciated,

Thanks

I assume the 3 is supposed to be a subscript.  Try this:

  b1 <- x <- y <- 1
  plot(x,y, main = bquote("Results for " ~ beta[3] ==.(b1)))

Are you looking for 

 plot(0,0, main= bquote(paste("Results for ", beta[3] ==.(b1))))

?

Your fundamental problem is that expressions need to be syntactically
complete, so "==.(b1)" with no left hand side gets you a syntax error.
However, you can supply a dummy, and

 plot(0,0, main= bquote(paste("Results for ", beta, 3, {} ==.(b1))))

does work (although possibly not with your desired output).

b1<-3
plot(1,1, main= bquote(paste("Results for ", beta==.(b1))))

seems to work.
