Examples

# Create PhysioExperiment with events
pe <- PhysioExperiment(
  assays = list(raw = matrix(rnorm(1000), nrow = 100)),
  samplingRate = 100
)
events <- PhysioEvents(
  onset = c(1, 2, 3),
  type = c("stimulus", "response", "stimulus")
)
pe <- setEvents(pe, events)

# Get all events
getEvents(pe)
#> PhysioEvents with 3 events
#> Event types: stimulus, response 
#>   onset duration     type value
#> 1     1        0 stimulus      
#> 2     2        0 response      
#> 3     3        0 stimulus      

# Get only stimulus events
getEvents(pe, type = "stimulus")
#> PhysioEvents with 2 events
#> Event types: stimulus 
#>   onset duration     type value
#> 1     1        0 stimulus
