i have download a dataset from GEO i.e in TAR file format.. i dont know how to open that data in R.
GEO is a big data archive, depending on what kind of file you have downloaded, its better to pre-process (extract/sanity check) on command line and then proceed to R. If you are doing it routinely, better is check SRAdb pakage.
Using the SRAdb Package to Query the Sequence Read Archive
Use the function untar in R
Extract the contents of the tar file first?
tar -xzf "filename.tar.gz"
And this is not a bioinformatical question. A simple google search of 'tar files' would've explained it.
Does that work in R?
It's bash command line. I was questioning why not just extract the .tar before attempting to process it
I know, but the question was how to open in R right?
