checkSetup: check setup

Description

checkSetup will do some sanity checks on input data provided through object.

Usage

checkSetup(object, quiet = FALSE)

Arguments

object

object, to be passed to preProcess, see intamap-package

quiet

logical; TRUE to suppress OK statement

Value

• returns TRUE if check passes, will halt with error when some some error condition is met.

Details

checkSetup is a function that makes certain tests on the intamap object to make sure that it is suited for interpolation. Particularly, it will issue a warning or an error if one of the following conditions are met:

• observationsis not an element ofobject
• observationscontain less than 20 observations
• Some of the observation locations are duplicated
• formulaStringis not an element ofobject
• None of the columns ofobservationshas a name that corresponds to the independent variable offormulaString
• predictionLocationsis not an element ofobject
• predictionLocationsis not aSpatialobject
• targetCRSis given, butobservationsandpredictionLocationsdo not have CRS set
• addBiasincludes biases that are not part ofremoveBias

The function will issue a warning if it appears that predictionLocations and observations share a small region. This warning is given as it is a likely cause of errors, although it can also happen if predictionLocations are limited to one small cluster.
