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.
Since you provided no workable example, I am just using the second
example in the help page to illustrate specifying col, lwd, and lty:
> with(ToothGrowth,interaction.plot(dose, supp, len, fixed=TRUE, col
= c("red","blue"), lty=1, leg.bty = "o"))
> with(ToothGrowth,interaction.plot(dose, supp, len, fixed=TRUE, col
= c("red","blue"), lty=1,lwd=3, leg.bty = "o") )
It appears that lwd is not passed on to the legend call.
You should carefully review the help page for further information and
details:
