Dear All,
Is it possible to export transformed data from the lumi package? I
want to
use the data in another statistical program and export it from R as an
.txt
file. I've tried write.table command but it does not work on batch
objects.
I could export expression values by using temp <- exprs(lumi.T) but
the file
does not include gene names.
The data I want to export has been produced like this (lumi version
1.10.2):
smctarget <- 'H:/Geeniekspressio/Illumina_files/targetidsmc.txt'
smctarget.lumi <- lumiR(smctarget, detectionTh=0.01, QC=TRUE,
inputAnnotation=FALSE, checkDupId=FALSE, lib='lumiHumanAll')
lumi.T <- lumiT(smctarget.lumi, method=c('log2'), ifPlot=TRUE)
or with a command used to normalize the first data:
lumiqtlog2.N <- lumiN(lumi.T, method='quantile', verbose=TRUE)
What I would like to export is expression values from the object
lumi.T or
lumigtlog2.N. I would like the data to include the targetID names and
the
expression values after transformation or after
transformation+normalization
from each of the chips in the data.
Could anybody help? Are there help pages available which address this
issue?
