calculates area of peak from discrete signal and time measurements can deal with time points out of order as long as time and signal indices are matched

calculate_area(t, y, tstart = NULL, tend = NULL, const_dt = FALSE)

Arguments

t

the time points
y

the signal data
tstart

the starting time of the signal to integrate, NULL (default) starts with the signal from the first time point
tend

the ending time of the signal to integrate, NULL (default) ends with the signal at the last time point
const_dt

if the time interval between data points is knonw to be constant use TRUE to make the computation slightly faster (~2-3 times with peaks 10,000 data points wide), default is FALSE

Value

integrated area in units of [y units][t units]
