Description

arguments for index th_topt

Usage

## S3 method for class 'th_topt'
index_arguments(
  climindvis,
  threshold,
  threshold2,
  iformat = "perc",
  NAmaxAgg = 20,
  trend = FALSE,
  NAmaxTrend = 20,
  fyear = FALSE,
  ...
)

Arguments

climindvis	Object of type climindvis as returned by make_object which must contain the variable average temperature (tavg)
threshold	Threshold value in degrees C for threshold <= tavg <= threshold
threshold2	Threshold value in degrees C for threshold <= tavg <= threshold2
iformat	Format for indicator "perc"(default)/"days"
NAmaxAgg	Maximum number of missing values in daily data of each aggregation period (e.g. in all January values for the whole time series). Value between 0 (=0%; no missing values allowed) and 100 (=100%; all values can be missing values). If the number of missing values is higher than NAmaxAgg the index value for the respective grid point/station is set to NA. Default = 20 (20%).
trend	Logial (or character). Calculates trends with a predefined method for the chosen index. For information on default method, see trend_methods. You can chose to calculate a non-parameteric trend, by setting trend to a character string "MannKendall". This calculates a TheilSen slope and MannKendall test. Default = FALSE.
NAmaxTrend	Maximum number of years in time series of index which are missing values. Value between 0 (=0%); no years with missing values allowed) and 100 (=100%); all years can be missing values). If exceeded, the trend is set to NA for the respective grid point/station. Note that the value is relative to the length of the time series. Default = 20 (20%).
