| Quantlet: | dispdotcl | |
| Description: | generates a dotplot with tonal highlighting of classified data. |
| Usage: | dp = dispdotcl(gr, fr, inColorScheme) | |
| 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 | |
| inColorScheme | k x 3 vector (discrete) of RGB colors for the different highlighting stages | |
| Output: | ||
| dp | composed graphical object | |
2) Data are uniformly spread inside their intervals and are plotted afterwards. Compare it to dispdotcl2.
