Hello I have a counts file and I want to make a DGEList object from it. The counts file contains the tags and all the samples of experiment(first column is for tags and other columns are the samples), but I do not want to make my object from all the samples for exapmle I need only 20 of the samples. where can i determine it? -- output of sessionInfo(): for example if i want to use the readDGE function : d <- readDGE(myfile, , ) but i do not want all the columns from my files just some of them. how can i specify? -- Sent via the guest posting facility at bioconductor.org.
