baselineabif {seqinr} | R Documentation |
Estimation of baseline value
Description
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.
Usage
baselineabif(rfu, maxrfu = 1000)
Arguments
rfu |
a numeric vector of signal value |
maxrfu |
signal values greater or equal to maxrfu are forced to NA |
Value
A single numeric value for the estimated baseline.
