Load large Datamatrix with column and rownames

I need to read multiple large DataMatrices from a tsv into julia. They have column AND rownames. Do I have to realy read it in first and then slice the first column? What would be the best approach

If you’re trying to read your data in without the row names, you should be able to use the select argument to CSV.File.


Okay, thank you. Are you implying that there is a way to read them in similar to pandas.indices?

I’m not familiar with pandas, but select allows you to pass a function indicating whether or not to read a column.
