Master data frame or so
It sounds like just a simple list object will do what you want. What you will have to specify is exactly what you thing the structure might contain and then how you want to access it, and then possibly how you want to update it on an ongoing basis.

Dear sir/madam,
I have been using R for a while now for microarray analysis, and I would
like to make a "master" data frame in which I can combine information from
many different sources. The basic list a genelist with 25.000 probes, then I
would like to have a subcompartment with the statistical information, a
subcompartment with more extensive information regarding each gene, and then
the output from several clustering programs, which group a number of genes
and relate those to a function. In my mind this file looks like:
Genelist: c("ILM1"," ILM2", "ILM3", "ILM4")
@Statistics
$p.value (0.01, 0.002, 0.0004, 0.006)
$fold.change (2, 4,3, 0.5)
@Moreinfo
$("HemoglobinA1", ?"Myosin1", ?"Myosin2", " HemoglobinB1")
@Functions
$Blood("X", "", "", ?"X")
$Muscle("", "X", "X","")
I have no idea how to make such a file. I have been reading about matrices,
data.frames, S4-objects, but I don't know how to do it. Can anyone help me
with this?
Many thanks in advance!
Kind regards,
Inge Holtman
