\usage{

updateFarmData(
  filename,
  BINDir,
  gdxmap,
  mapping,
  writegdx = TRUE,
  cptcoeffs = FALSE,
  farmchars = NULL,
  cptcoeffsxl = NULL
)

}
\arguments{
\item{filename}{Name of the GDX file with BIN data and mappings.}

\item{BINDir}{Directory where the FADN data is located.}

\item{gdxmap}{Name of the set in the GDX file that contains the mapping (e.g. Regs2BINID)}

\item{mapping}{Column name of the characteristic/variable to be grouped by (e.g. "Regions" or "Regs")}

\item{writegdx}{Logical. If `TRUE`, it writes a GDX with the descriptive statistics.}

\item{cptcoeffs}{Logical. When this is set to `TRUE` it calculates farm-specific parameters based on CPT coefficients}

\item{farmchars}{GDX file containing farm characteristics}

\item{cptcoeffsxl}{Location of the CPT coefficients excel file}

}
\value{
A tibble `tbl_df`.
}
\description{

`updateFarmData()` creates sample farms by aggregating data based on the weighted mean and the selected mapping for use in FarmDyn.

For non-numerical globals, it summarises based on the mode using the `Modes()` function. When `writegdx` is `TRUE`, it writes the GDX in the format 'farmData_(mapping).gdx'.
