| Description: | generates a standard boxplot for a classified data set. |
| Usage: | bp = dispboxcl(gr, fr) | |
| Input: | ||
| gr | m x n grid matrix, each column must be ordered ascendently | |
| fr | (m-1) x n matrix of frequencies for each interval in each column | |
| Output: | ||
| bp | composed graphical object | |
2) It generates a boxplot with median line and upper and lower edge of the box representing the upper and lower quartile. The whiskers designate the farest non-outliers above resp. below the box. Outliers are all data at least 1.5 * (height of box) away from the upper resp. lower edge of the box and are plotted as circles. If this distance exceeds 3 * (height of box), a star symbol is used ("gross outlier").
