Subject: Master data frame or so
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
