TCGA -derived Large RangeSummarizeExperient file

Question

[Tom]

Hello, I am analyzing TCGA data by R.

A Large RangeSummarizeExperient file was available now. And the packages of SummarizedExperiment and GenomicRanges were used to analyze the data file.

The function of rowDate was used to get the sample information, by which a Large DFrame was generated

(Fig 1).

I would like to take several items from the Large DRrame

(Fig. 2).

I am taking a single item individually. It is a little time-consuming. Is there a simple way to do that. Thanks a lot !

For the end user these DFrames are just regular data.frames, so you can do col_data[,c("barcode", "patient", "whatever")] or just do as.data.frame(col_data). Does that help?

It works well. Thank you very much ! ATpoint
