colors <- c("red", "blue", "darkgreen", "gold", "black")
labels <- c("3/02/2012","12/30/2011","4/20/2012")
In plot I use
{
plot(x, hx1 , type="l", lwd=2, tck=1, col=colors[1], ylim=c(0, maxhx), xlab="x
value", ylab="Density", main="AAPL")
.
.
.
labels, lwd=2, lty=c(1, 1, 1, 1, 2), col=colors)
}
It looks like qplot uses
colour=colors
to pickup colors.
At the R console type
colors()
For a list of color names and numbers.
Hope this helps.
