I have been carried out a ordination programm, which is db-RDA based on package "vagan". I could show the ordination figure. However, I do not find how X and Y values of the respective plots and of arrows of the respective environmental variables were taken. Please teach me the way(s) and programm(s) to get the X and Y values.

Hello,

They are extracted from the result object using scores() function. The scores() function is described together with the plot() function (see ?plot.cca, ?scores.cca). The raw scores can be found from the result object (see ?cca.object), but scores() also scales results as requested (argument 'scaling').
