Dear Uwe,
Sorry, I did not describe my question clearly. I created a matrix to
store color code using rgb function.
abc = rgb(6:36,0,0,maxColorValue = 255)
And after running codes like this
for (i in c(1:20))
{
points(...,...,col=abc[i])
lines(...,col=abc[i])
}
R still used 8 colors of abc color codes repeatedly to draw the diagram
Any helps?
Best Regards...
