[BioC] Error message in imageplot of limma packages

[Joyce Gu]

Hi,
I tried to use imageplot to see my normalized data in limma package, I tried 
both command as following,
> imageplot(log2(RB$Rb[,1]),RB$printer,low="white",high="red")
and
> imageplot(MA$M[,1],RB$printer,zlim=c(-3,3))
and
>imageplot(MA$M[,1],layout=list(ngrid.r=12,ngrid.c=4,nspot.r=21,nspot.c=21))

they all gave me the same kind of error messages:
Error in imageplot(log2(RB$Rb[, 1]), RB$printer, low = "white", high = "red") 
:
        Number of image spots does not agree with layout dimensions

Or
Error in imageplot(MA$M[, 1], RB$printer) :
        Number of image spots does not agree with layout dimensions

Any idea is greatly appreciated!
Thanks
