[BioC] problem in diagnostic plots?

[Peter Baker (CMIS, Indooroopilly)]

Hi All

I've just started using Bioconductor and seems really good.

As a test, I've read in two GenePix files - essentially the same code
as ReadSpot example and seem to be able to plot, print, normalise ....

The only problem I've encountered is

> maDiagnPlots1(test[,2])
Error in plot.new() : Figure margins too large
> maRawPlots(test[,2])
Error in plot.new() : Figure margins too large
> maNormPlots(test[,2])
Error in maMloc(structure(list(), maRf = structure(c(4109, 771, 3073,  : 
	No direct or inherited method for function "maMloc" for this call

I get the first plot only - seems to stop at the second

Does anyone recognise this sort of problem?

Could it be missing values? Do I need to filter these in some way
before plotting? The arrays have row 10 of each 'block' empty

------------------------------------------------

However, plots like these work absolutely fine

### backgrounds
maImage(test[,1], x = "maGb", contour=TRUE)
maImage(test[,1], x = "maRb", contour=TRUE)

### raw images
maImage(test[,1])

Thanks for your help
