The default Circos units for RCircos. A Circos unit is a point which represents an inteval of genome length on the circumustance of a circle line. By default an unit represents a point which equal to the length of 30000 base pairs and length of human genome is used to calculate the total number of Circos units. This is a read only parameter and is for internal use to modify plot parameters for RCircso plot with non-human genomes.
