General Errors Detection

Usage

GeneralErrorsDetection(Data)

Arguments

Data

Dataset (data.frame or data.table)

Value

The input dataset (data.table) with a new Comment column with error type informations.

Details

Detect errors

  • Remove duplicated rows

  • Check missing value in X-YTreeUTM/PlotArea/Plot/Subplot/Year/TreeFieldNum/ IdTree/IdStem/Diameter/POM/HOM/Family/Genus/Species/VernName

  • Check missing value (NA/0) in the measurement variables: "Diameter", "HOM", "TreeHeight", "StemHeight"

  • Check of the unique association of the IdTree with plot, subplot and TreeFieldNum (at the site scale)

  • Check duplicated IdTree/IdStem in a census (at the site scale)

  • Check for trees outside the subplot (not implemented yet)

  • Check invariant coordinates per IdTree/IdStem

  • Check fix Plot and Subplot number (not implemented yet)

Examples

library(data.table)
data("TestData")
