Hello, my dataset is already aggregated: I have two categorical variables, say "continent" and "country" and one non-negative metric variable "population". Now I would like to produce a mosaic plot which uses "population" to determine how large each area of the plot is. In other words, I fail to find out - how to use the mosaic function of the vcd package without using table, - or I do not know how to convert my dataset into a table (as.table fails) As an example, here a simple dataset: Continent; Country; Population Europe; France; 65 Europe; Germany; 80 Africa; Algeria; 32 .... Can you help me to get started?
You can create the tables by xtabs(Population ~ Continent, data = mydata) etc. which can then be visualized using mosaic() in the usual way. hth, Z
