utils_time_keywords(tsl = NULL)

Arguments

• tsl: (required, list) Time series list. Default: NULL

Returns

Character string, aggregation keyword, or "none".

Examples

#one minute time series
#-----------------------------------
tsl <- tsl_simulate(
  time_range = c(
    Sys.time() - 60,
    Sys.time()
  )
)

#valid keywords for aggregation and/or resampling
utils_time_keywords(
  tsl = tsl
)

#10 minutes time series
#-----------------------------------
tsl <- tsl_simulate(
  time_range = c(
    Sys.time() - 600,
    Sys.time()
  )
)

utils_time_keywords(
  tsl = tsl
)

#10 hours time series
#-----------------------------------
tsl <- tsl_simulate(
  time_range = c(
    Sys.time() - 6000,
    Sys.time()
  )
)

utils_time_keywords(
  tsl = tsl
)

#10 days time series
#-----------------------------------
tsl <- tsl_simulate(
  time_range = c(
    Sys.Date() - 10,
    Sys.Date()
  )
)

utils_time_keywords(
  tsl = tsl
)

#10 years time series
#-----------------------------------
tsl <- tsl_simulate(
  time_range = c(
    Sys.Date() - 3650,
    Sys.Date()
  )
)

utils_time_keywords(
  tsl = tsl
)
