[BioC] Writing own package description.

[TEXTORIS Julien]

Hi,

i've learn through the many tutorials and courses available on the net 
(thanks to everybody for that, it's wonderfull), and i really like 
working with bioc.

I work in a lab where we use a cDNA, home made chip. I was wondering how 
i could write a package for R to describe this particular chip, and use 
all the possibility of bioconductor with it, because all that i learned 
with tutorials was with affy chips.

I've read some documents but i'm still a bit confused about that.
The exprset structure is for data, isn't it ? So in it, i'll put results 
from my experiments, and also phenoData. But i also need to describe 
which probe correspond to which gene ? no ?


How could i start ?

thanks for your answers.
