Oggetto: [R] How to plot this
Hi there,
I produced a plot using the following codes:
y<-rnorm(1000, 2, 0)
x0<-c(0, 0)
y0<-c(0, 0)
y1<-c(0, 1)
x1<-c(0, 4)
plot(density(y), ylab="Abundance of species", xlab="Environmental
gradient", main=" ",
xlim=c(0, 4), ylim=c(0, 1), lty=2, col=4, xaxt="n", yaxt="n",
frame.plot=F)
lines(x0, y1) # add an axis
lines(x1, y0) # add an axis
arrows(3.95, 0, 4, 0, angle = 15, length = 0.1)
arrows(0, 0.98, 0, 1, angle = 15, length = 0.1)
Please help me to remove the grey horizontal line and put the axis
labels closer to the axes. And also appreciate any
suggestions on how to
make those arrows look nicer, e.g. a filled small arrow for each axis,
like what from points(0, 1, pch=17), but a slightly narrowed one.
Thanks.
Regards,
Jin Li
