Normalization of non-normalized .txt data from GEO

Question

[garimav89]

I have downloaded a non-normalized .txt file from GEO and now want to do median and quantile normalization and background normalization of this data.

My .txt file looks like this:

ID_REF 1A 1B 2A 2B hsa-miR-199b-3p 328 1532 1136 288 hsa-miR-302c -88 -44 -104 -136 hsa-miR-499-5p -24 -40 -48 -104 hsa-miR-768-3p 1032 1841 1424 848

Can anyone share R-script to proceed with the normalization step? Your help is really appreciated.

Thanks

Googling will easily get you what you need, for example start with the following workflows:

I wonder if anyone had success using info from these URL to normalise non-normalized .txt file from GEO. I went through the URL to no avail. Please help you have and R-Script.
