Examples

# Create example data
pe <- PhysioExperiment(
  assays = list(raw = matrix(rnorm(400), nrow = 100, ncol = 4)),
  colData = S4Vectors::DataFrame(label = c("Fz", "Cz", "Pz", "Oz")),
  samplingRate = 100
)

# Write to temporary CSV file
tmp <- tempfile(fileext = ".csv")
writeCSV(pe, tmp)

# Write in long format
writeCSV(pe, tmp, format = "long")

# Clean up
unlink(tmp)
