Dear all,
I want to plot 8 chemical variables in the same plot. I have used the
interaction.plot command:
> interaction.plot(speclong$Date,speclong$time2,speclong$outcome,xaxt="n",type="l",pch=20,xlab="",
> log="y", ylab="Concentration (ug/L)",trace.label="",col=rainbow(8))
However, what it gives me is dotted lines and the colours are very fade. I was
wondering if I can change the lines to be solid and as well to specify for each
line the colour that I want.
Thanks a lot.
