While quantitative environmental variables can best be represented on a biplot as a vector (see Correlation of Env. Vars) some environmental variables such light or dark are best coded as a 0 or 1. These are termed binary variables (see Dummy Environmental variables ). Such variables can be represented on a biplot as a vector but are best displayed as a single point - a centroid. This grid gives the co-ordinates of the binary variables in the data set. N/A (for not applicable) is marked beside quantitative environmental variables.
