Description

The function compares the observed

Usage

check_individual_weightTC(DataTC,LW=NA,year,wd,suffix,verbose=FALSE)

Value

The file Comparison_estimated_observed_weight_in_TC.csv is automatically saved in the working directory in order to easily detect the samples with this differences in total weight. For all the records the percentage difference between observed and estimated weight is reported.

Arguments

DataTC

Biological data table according to MEDITS protocol (TC)

LW

year

reference year for the analysis

wd

working directory path defined by the user
