DMC_DEMO.R

To quantify sampling coverage, we developed a box-counting method, the Dynamic Match Coefficient (DMC), which quantifies how much a set of occurrences of a given species matches with its geographic range or climatic niche. DMC is the area under the curve measuring the match between occurrence data and background reference (geographic range or climatic niche) across grids with variable resolution. High DMC values indicate good sampling coverage.<br>Here we provide the R code for DMC calculation with an application example.Range.dbf contains xy coordinates of occurrences of a example species. Plots.dbf contains xy coordinates of vegetation plots where the given example species occurres in.
