In obaezvil/SpatIndex: Calculate spatially distributed hydroclimatological indices

Utils function to compute the SPI or SPEI using a vector. This function is based on the code presented in the SPEI package from 'sbegueria' https://github.com/sbegueria/SPEI/blob/master/R/spei.R

Description

Utils function to compute the SPI or SPEI using a vector. This function is based on the code presented in the SPEI package from 'sbegueria' https://github.com/sbegueria/SPEI/blob/master/R/spei.R

Usage

.spei_daily.spei(
  params_matrix,
  P_matrix,
  pze_matrix,
  trgt,
  distribution,
  dates
)

Arguments

params_matrix	matrix obtained from the parameters list
P_matrix	matrix of the required P layer
pze_matrix	matrix of the probability of zero layer
trgt	The day for which the function will be computed. The default is NULL, indicating that the last day of the data will be selected.
distribution	Character value indicating the name of the distribution function to be used for computing the SPI (one of 'log-Logistic', 'Gamma' and 'PearsonIII'). Defaults to 'log-Logistic' for SPEI.
