Hi Ng,

on R, try

  help.start()

on the html page opened, choose Packages, limma

on limma help page, choose the function you want, i.e. imageplot

on imageplot help page you will find something like this:

Usage
imageplot(z, layout, low = NULL, high = NULL, ncolors = 123, zerocenter = NULL,
zlim = NULL, mar=c(2,1,1,1), legend=TRUE, ...)


a few lines below you can find this:

... 	any other arguments will be passed to the function image

a more few lines below, on "See Also" section, there is a link to
image help page.

on image function help page you will find something like this:

Usage
image(x, ...)
## Default S3 method:
image(x, y, z, zlim, xlim, ylim, col = heat.colors(12),
      add = FALSE, xaxs = "i", yaxs = "i", xlab, ylab,
      breaks, oldstyle = FALSE, ...)

... 	graphical parameters for plot may also be passed as arguments to
this function, as can the plot aspect ratio asp and axes (see
plot.window).

If you visit the plot function help page you will find this:

main
    an overall title for the plot: see title.
sub
    a sub title for the plot: see title.
xlab
    a title for the x axis: see title.
ylab
    a title for the y axis: see title.

So, you could try, for imageplot:

imageplot(MA$M[,1], RG$printer, zlim=c(-3,3), main="Your Main Graph
Title Here", sub="Your sub graph title here")

You could find the same for the others two functions.

Hope this help!

Best wishes
