R help - Aug 2013 - corrgram (package corrgram): how to plot multiple correlograms in the same page?

Hello,

I am trying to plot a few correlograms on the same figure, with the function
corrgram() from the package corrgram.  However, the function does not seem to
use the base graphic system, as setting out the multiple figure layout with,
e.g., par(mfrow=c(2, 2,)) does not work.

Does anybody know a workaround for this?

Many thanks in advance for any advice

best
giuseppe

When you are using a package from CRAN, you should probably contact the
author of the package (in this case, that is me) with questions, instead of
asking on R-help.

The corrgram package DOES use base graphics.  For instance, when using 3
variables, each one of the squares of the corrgram is using one 'plot'
of
par(mfrow=c(3,3)).

What you are trying to achieve may theoretically be possible using the
gridBase package, though I have not been able to construct a working
example, perhaps because corrgram() changes par() inside of the function.

Here's an example that works for simple scatterplots.

require(grid)
require(gridBase)

gl <- grid.layout(2, 2, widths=unit(c(3, 3), "inches"),
          heights=unit(c(3, 3), "inches"))
pushViewport(viewport(layout=gl))
grid.newpage()
unit. <- unit(c(1,1), c('null','null'))
pushViewport(viewport(layout=gl))
for(i in 1:2) {
    for(j in 1:2) {
        pushViewport(viewport(layout.pos.row=i, layout.pos.col=j))
        par(fig=gridFIG())
        par(new=TRUE)
        grid.rect(gp=gpar(lwd=3, col=i+j))
        plot(1:10)
        #corrgram(dat) # not working...
        popViewport()
    }
}
