baselineabif {seqinr} | R Documentation |
This function tries to estimate the baseline value for RFU data from capillary electrophoresis whith the heuristic that the most common value is the baseline.
baselineabif(rfu, maxrfu = 1000)
rfu |
a numeric vector of signal value |
maxrfu |
signal values greater or equal to maxrfu are forced to NA |
A single numeric value for the estimated baseline.
