create_phys_var

Source: R/create_phys_var.R

creates data for each wrangling step of the physiological variable using the data wrangling functions: detrend(), upsample(), and deconvolve_afni()

create_phys_var(
  phys,
  detrend_factor,
  upsample_factor = NULL,
  hrf,
  afni_path = NULL,
  afni_quiet = FALSE
)

Arguments

phys

time series data
detrend_factor

factor to detrend the time series
upsample_factor

factor to upsample the time series for the deconvolution step (default: NULL)
hrf

hemodynamic response function (hrf) time series data
afni_path

path to afni directory (default: NULL)

Value

a list of datasets for each data wrangling step of the physiological variables
