I added code markup to your post for increased readability. You can do this by selecting the text and clicking the 101010 button. When you compose or edit a post that button is in your toolbar, see image below:

This looks pretty clear, or at least suggest you that the first column of pData (pheno_data?) should match the names of the folders containing the ballgown data.

Your command above is also incomplete: you never show us how you call the ballgown() function.

Sorry, I thought I had it earlier.
This is how I called the ballgown () function:
 bg <- ballgown(dataDir="/fast/users/a123456/Ballgown/prr_bulk", samplePattern="B", pData=pheno_data)
