Examples

soma_file <- extractSampleData()
wide_soma_data <- readAdat(soma_file)

# Indexing returns a data.table, so the WideSomaLogicClass is preserved
wide_soma_data[1:5, list(`SeqId.3896-5_2`)]
# Indexing simplifies to a numeric vector, so the class is lost
wide_soma_data[1:5, `SeqId.3896-5_2`]

# Ignore the intensity columns (as per getSampleData)
j <- !colnamesStartWithSeqId(wide_soma_data)
wide_soma_data[1:5, j, with = FALSE]
unlink(soma_file)
