R help - Feb 2003 - Background color of plot

I'm using the parameters "mfrow" and "mfg" to display
some graphics(plots)
at the same time. Although, because of the parameter "mfg", the
parameter
"bg" don´t change the background color.

What can I do to solve this?


Here is the code I'm using...

...
     i <- 1
     for(j in 1:4){
         for(k in 1:2){
                     limiares <- tabLimiar(arrayMetricas[,i])
                     op <- par(mfrow=c(4,2),pty="s")
                     par(mfg=c(j,k))
                    
plot(limiares,main=a[i],ylab="frequencia",xlab="limiares",bg="white",col="green",col.main="seagreen",type="b")
                    
box(which="figure",lty="solid",col="white")
                     par(op)
                     i <- i+1
                     if(i == ncol(arrayMetricas))
                        break
         }
     }
...

Set it in par() as in the following example:

  par(bg="green", mfrow=c(2, 1))
  plot(1:10)
  plot(1:10)
