[BioC] problem with arrayQuality in OSX 10.5

["M. Gonzalo Claros Díaz"]

Hi:

I was using arrayQuality library for months in R in mac OS 10.4  
without problems. Now I have an Intel mac with OS 10.5 and I have  
problems with arrayQuality functions: they do not start. This is the  
transcription:


gpQuality(RGdata$targets$FileName)
[1] "Starting gpQuality..."
Error en X11(paste("png::", filename, sep = ""), width, height,  
pointsize,  :
   no fue posible iniciar el dispositivo PNG
Además: Warning message:
In png(filename = "qualPlot.50-51/Slid50-COM3-LAT5Total Baja-A.png",  :
   no fue posible abrir el archivo PNG 'qualPlot.50-51/Slid50-COM3- 
LAT5Total Baja-A.png'

traceback()
3: png(filename = "qualPlot.50-51/Slid50-COM3-LAT5Total Baja-A.png",
        width = 800, height = 600, units = "px", pointsize = 12,
        bg = "white", res = NA)
2: do.call(dev, maDotsMatch(maDotsDefaults(opt, c(list(filename =  
plotname),
        plotdef$dev)), formals(args(dev))))
1: gpQuality(RGdata$targets$FileName)


On the contrary, a command like

	maQualityPlot(RGdata)

works perfectly.

¿Do someone have any idea?

Gonzalo
