[BioC] Problem with exporting graph from plotPCA() in a DESeq2 function

Hi!

I am currently programming a function for easy use of DESeq2. I would like to export my graphs with the pdf() command. It works fine for the dispersion graph and other volcano plots that I programmed, but I encountered some problems with the plotPCA() function. First I have to execute it at the very end of the function to see the graph, and the if I use pdf()... dev.off / graphics.off(), the pdf file contains all graphs but the PCA graph.
I tried it line by line in the console, it works fine.
I usually work with RStudio, but under R it didn't work either. Any ideas?

Thanks for your help,

Fabrice.
