I would like to use lumi package for normalize to http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE31699

I read csv file and get a matrix file. I tried to use the steps in http://www.bioconductor.org/packages/release/bioc/vignettes/lumi/inst/doc/lumi.pdf but it doesn't work.

My questions:

How can I normalize to the my matrix file?
What should I do for using this package?

Thanks in advance

Why do you want to normalize the matrix file ? Its already normalized -

"The data was preprocessed by Bioconductor lumi package (version 2.5.5). It was vst transformed and quantile normalized."

Thank you very much for your information. I am very new about bioinformatics and R so these knowledge is very helpful for me.

I look at there its useful for expression data analysis and I check my matrix and your saying data is not same. it is for just 1 sample but I have 36 samples. I have raw data matrix both methylation data and expression data so I have to normalized. actually doesn't matter be which packet lumi or others. I just want to normalized these matrix and than according to distribution (normal- non normal) I will use parametric tests. I will be most grateful, if you could help me.
