tsRim-class {TargetSearch} | R Documentation |
This is a class to represent retention index markers.
Objects can be created by the function ImportFameSettings
or by calls
of the form new("tsRim", limits = [two column matrix with time limits],
standard = [a vector with RI standards], mass = [m/z marker])
.
limits
:"matrix"
, two column matrix with lower and upper
limits where the standards will be search. One row per standard. standard
:"numeric"
, the marker RI values. mass
:"numeric"
, the m/z marker. rimLimits
signature(obj = "tsRim")
: gets the time limits. rimLimits<-
signature(obj = "tsRim")
: sets the time limits. rimMass
signature(obj = "tsRim")
: gets the m/z marker. rimMass<-
signature(obj = "tsRim")
: sets the m/z marker. rimStandard
signature(obj = "tsRim")
: gets the standars. rimStandard<-
signature(obj = "tsRim")
: sets the standars. Alvaro Cuadros-Inostroza, Matthew Hannah, Henning Redestig
