ptrvSignificantSNRIons

Description

ptrvSignificantSNRIons

Usage

ptrvSignificantSNRIons(
  dataset,
  method = "max",
  referenceBreath,
  noisePeriod = c(0, 30),
  correction = "cycle",
  multiplyNoiseBy = 3,
  minimalDuration = 2,
  halfWindowSize = 5,
  smoothMethod = "MovingAverage",
  minExpi = NULL,
  maxInspi = NULL,
  forMinExpiDivideMaxIntBy = 5,
  forMaxInspiDivideMaxIntBy = 4,
  removeNoise = FALSE
)

Arguments

dataset	whose names are timeCol, Ion1,... ,Ionp.
method	"max" or "ttest" (TODO "tangente")
referenceBreath	name of the ion taken as reference for breathing
noisePeriod	vector with two numbers indicating the period corresponding to a blank period.
correction	"none" or "cycle". See Details.
multiplyNoiseBy	a number such as a ion whose maximal intensity during tasting/maximal intensity during blank period > multiplyNoiseBy is detected as significant (used for method=="max")
minimalDuration	minimalDuration of a breathing cycle (2 by default - as a accelerated breathing frequency corresponds to 20 cycles and more by minut and a low frequency is 12 and less -)
halfWindowSize	parameter used to determine the smooth for the peak-picking used in break detection
smoothMethod	NULL, "SavitzkyGolay" or "MovingAverage"
minExpi	minimal value for an expiry intensity to be detected as an expiry (blue dotted line in the plot).
maxInspi	maximal intensity of the original curve required to be considered as a breathing peak (purple dotted line in the plot)
forMinExpiDivideMaxIntBy	default to 5. When minExpi is null, it is evaluated as the ratio of the maximal intensity and forMinIntensityDivideMaxIntBy
forMaxInspiDivideMaxIntBy	default to 5. When minExpi is null, it is evaluated as the ratio of the maximal intensity and forMinIntensityDivideMaxIntBy
removeNoise	if TRUE, the noise is removed in the calculation of intensity by time
