get_event_years(
  x,
  scar_event = TRUE,
  injury_event = FALSE,
  custom_grep_str = NULL
)

Arguments

x	An fhx object.
scar_event	Boolean indicating whether years with scar events should be returned. Default is TRUE.
injury_event	Boolean indicating whether years with injury events should be returned. Default is FALSE.
custom_grep_str	Character string to pass a custom grep search pattern to search x "rec_type" column for. NULL by default.

• get_year() subset an fhx object to select years.

• get_series() subset an fhx object to select series.

• get_event_years() gets years for various events in an fhx object.

• count_event_position() count the number of different events in an fhx object.

• yearly_recording() count the number of "recording" events in each year of an fhx object.

Examples

data(pgm)
get_event_years(pgm, scar_event = TRUE, injury_event = TRUE)

# Passing a custom string to grep. This one identified recorder years:
get_event_years(pgm, custom_grep_str = "recorder_")

# Use with composite to get composite years:
comp <- composite(pgm, comp_name = "pgm")
event_yrs <- get_event_years(comp)[["pgm"]]
print(event_yrs)
