hello, I created a correspondence anlalysis plot with the ca package using the command plot(ca(mymatrix)). I got two different colours for the rows and the colums, like it is standard i gather. My question is, if it is possible to get more - for example 3 - different colours? In the following example, the question that parents were asked in a survey was: how often does your child eat hamburgers? I have got a frequency matrix for this question with the following colums and rows: never sometimes often always male female 3 to 4 years 5 to 6 years 7 to 8 years 9 to 10 years now I would like R to automatically create differnt colours for male and female on the one hand and the age of the children on the other hand. Thank you very much for your help in advance. Marion [[alternative HTML version deleted]]
