![]() None of these are strictly necessary for any analysis and meta data can therefore be safely ignored. It consists of location, date of the experiment, longitude, latitude, trial design, plot width and plot length. This meta data is used to store background information about the trials. If there is only one trial or no column trial is defined, the output will be a list with only one item. ![]() A TD object is a list of ames where each ame contains the data for a single trial. Split the data into separate ames by trial.For example, the column “genotype” is converted to a factor and “rowCoord” to a numeric column. Convert column types to the default column types.For example, the column in the data containing variety/accession/genotype is renamed to “genotype.” Original column names are stored as an attribute of the TD object. Rename columns to default column names used by the functions in the statgenSTA package.A TD object can be created from a ame with the function createTD.
