Hi All,
I have a scatter plot produced using ggplot2 and I want to add the
regression line to this scatter plot. I suppose I can use
geom_smooth() to do this, but for the sake of learning ( I am new both
to R and ggplot2), I want to try and add it as a function (something
that curve() does in the

Two problems I see. The first is the one described fairly clearly by

Hello Dear,
I am trying to plot a function to see a minimum point (actually, using
"optim"). For example,
1. y=f(x)
2. x has a range
3. plot(x,y) to see a point x minimizing y
I tried "plot(x,y)", but it made an error. Am I doing a right way?
Thanks,
Jin

Thank you for your replies. I figured out that curve has an option of add
which adds it to a previously existing graph.
Thank you,

Hi,
I have a histogram of an array of numbers.
hist(v,10)
How can I plot a function, say a semi circle,
curve(sqrt(2.25-x*x), -1.5,1.5)
in the same graph?
Thank you
