Search functions
climdex.tx10p
Computation of these percentiles involves use of a boostrap procedure, described below but described in more depth in [Zhang, 2005].
climdex.cwd
The
spells.can.span.years
option specifies whether spells can cross year boundaries -- i.e., span years. The default for this is the same as for fclimdex.
climdex.r10mm
Precipitation Exceeding 10mm Per Day
number.days.op.threshold
Number of days (less than, greater than, etc) a threshold
select.blocks.gt.length
Select blocks of TRUE values of sufficient length.
ec.1018935
EC example data
climdex.id
Icing Days
climdex.get.available.indices
Get available indices by name
spell.length.max
Maximum spell length
climdex.cdd
The
spells.can.span.years
option specifies whether spells can cross year boundaries -- i.e., span years. The default for this is the same as for fclimdex.
climdexInput.csv
Method for creating climdexInput object from CSV files
climdex.tnx
Monthly Maximum of Daily Minimum Temperature
climdex.tn10p
Computation of these percentiles involves use of a boostrap procedure, described below but described in more depth in [Zhang, 2005].

climdex.tx90p
Computation of these percentiles involves use of a boostrap procedure, described below but described in more depth in [Zhang, 2005].
climdexInput.raw
Any of tmin (daily minimum temperature), tmax (daily maximum temperature), tavg (daily mean temperature), and prec (daily precipitation) can be passed in. tavg will be derived from the mean of tmax and tmin if it is not supplied. If any of tmin, tmax, and prec are not supplied, the set of indices which can be calculated will be limited to indices which do not involve the missing variables.
climdex.wsdi
Warm Spell Duration Index
