[R] Putting obejct into Graph title

[hkimscil]

Hello all -

If I want to put mean value of a matrix into the title or subtitle of a graph, how would I do this? For example, in a set of commands like below,

> m.mean<-mean(m)
> gplot (m, thresh=m.mean)
> title (main="A2. Block Density of Matrix m\nplotted based on MDS", 
+    sub="lines below mean density (**0.435**) suppressed")

 I want to ask [R] to put the mean value (whatever it is, calulated as m.mean) into subtitle automatically, instead of my writing **0.435**. 

Is it possible?

Thanks!
