Hi Paola,

I'm forwarding your question to the Bioconductor mailing list where,
hopefully, someone will be able to help you.

I write you to have some  information about genefilter package. I am a
biologist and a pre-doc student, I must admit that I am quite new to 
data analysis and R. I'm analyzing Agilent single color gene expression 
and I'm using limma. I would like to filter my data and to identify the
detected genes in a % of my samples (something like the "Present" call). I
particular, I want to filter out the genes that have a lower expression 
than the background. I read that genefilter package has several methods for
filtering genes from microarray experiments, but I don't know which 
function of
the package should I use. Could you give me any information about this?
Thank  you very much for your support.

Kind regards,

Paola Orsini
