mlr_tasks_cookfarm_mlr3 | R Documentation |
The R.J. Cook Agronomy Farm (cookfarm) is a Long-Term Agroecosystem Research Site operated by Washington State University, located near Pullman, Washington, USA. Contains spatio-temporal (3D+T) measurements of three soil properties and a number of spatial and temporal regression covariates.
Here, only the "Profiles" dataset is used from the collection.
The Date
column was appended from the readings
dataset.
In addition coordinates were appended to the task as variables "x"
and "y"
.
The dataset was borrowed and adapted from package GSIF which was on archived on CRAN in 2021-03.
data(cookfarm_mlr3)
R6::R6Class inheriting from TaskRegr.
mlr_tasks$get("cookfarm") tsk("cookfarm_mlr3")
The task has set column roles "space" and "time" for variables "Date"
and
"SOURCEID"
, respectively.
These are used by certain methods during partitioning, e.g.,
mlr_resamplings_sptcv_cstf
with variant "Leave-location-and-time-out".
If only one of space or time should left out, the column roles must be
adjusted by the user!
