writeWignerData(
  x,

  t = 300,
  outDir = ".",
  mode = "nparray",
  progress = TRUE,
  ...
)

Value

A list with two items: files - a vector of file names for the Wigner data that were successfully created, any that were not able to be written will be NA, and warnings, a list with items containing event IDs that triggered any warnings

exStudy <- setSpecies(exStudy, method='pamguard')
if (FALSE) {
# not running because files are written to disk
wigFiles <- writeWignerData(exStudy, outDir = 'WigFolder')
}
