convert4aLFQ {SWATH2stats} | R Documentation |
This function selects the columns necessary for the aLFQ R package.
convert4aLFQ(data, annotation = TRUE, check_transitions = TRUE)
data |
A data frame containing the SWATH data in transition-level format |
annotation |
Option to indicate if the data has been annotated, i.e. if the columns Condition, Replicate, Run are present. If option is set to true it will write a new run_id as a string of the combination of these three columns. |
check_transitions |
Option if number of transitions should be checked. As input only transition-level data should be used and therefore this is checked. However, this makes the function slow and herewith be omitted. |
Returns a data frame in the appropriate format for aLFQ.
