euptfFun: Wrapper to predict and calculate prediction uncertainty for...

In tkdweber/euptf2: R package of updated European hydraulic pedotransfer functions (euptf2)

Description

Wrapper to predict and calculate prediction uncertainty for the soil hydraulic properties.

Usage

euptfFun(
  ptf,
  predictor,
  target = "THS",
  query = "predictions",
  quantiles = c(0.05, 0.25, 0.5, 0.75, 0.95)
)

Arguments

ptf	A character specifying the ptf. Permissible are "PTF01" "PTF02", ...., "PTF32".
predictor	A data.frame or data.table of dimension m x n, with m observations and n predictor variables. The column names specify the names of the predictor variables. At least DEPTH_M and USSAND,USSILT, USCLAY have to be provided. If in doubt, which PTF to select, use the function which_PTF first, to determine the suggested ptf, based on the available predictor variable.
target	one of the soil hydraulic parameters: THS, FC_2, FC, WP, AWC_2, AWC, KS, VG, or MVG.
query	either predictions to compute the mean of the response variable or quantiles which results in quantile predictions to describe uncertainty of the prediction.
quantiles	a vector of numeric values for calculating the quantiles at

Value

• a data.frame with predicted target variables if no quantiles are predicted.

• a list with predicted target variables if quantiles are predicted.
