Dear R-Users,
I would like to color the data in a splom according to their position in the matrix, i.e.
I would like to have all data shown in the upper left corner to be blue, all entries
below that to be black, and the data to the right to be all red. I tried to color the
"splom" with the following call...
splom(~iris[1:3],col=c("black","blue","red"))
...however, the colors are mixed. I also constructed a matrix containing the
required colors, but that also did not work. How do I color the splom according
to the location in the matrix as mentioned above?
Do you mean color by the levels of Species?
splom( ~ iris[1:3], col = c("black","blue","red")[iris[,4]])
Best wishes,
Uwe
Cheers,
Marius
