Calculates the resistance index, and further described in following publication ... [clinmon: An R package for calculation of clinical monitoring indices (2020)]

Usage

RI(df, del = NULL, trigger = NULL,
      blocksize = 3, freq, blockmin = 0.5,
      output = "period")

Arguments

df

Raw recording with data in 2 columns: time (in seconds) and CBFv measurement (e.g. MCAv, raw measurement). [dataframe]

del

# NOT RUN {
  data <- data.frame(time=seq(1, 901, 0.01),
                      pres=rnorm(90001))
  RI(df=data, freq=100)
