r graphing

thank you so much..

is it possible to make arrows show up at the end of axis.. and make
numberings show up in the middle axis??

Alternatively, you can use

curve(x^3, from = -5, to = 5); abline(h = 0, v = 0, lty = 2)

which will work even if the axes aren't in the middle of the image.

Please reply all to the list and don't send HTML.

curve(x^3, from = -5, to = 5); grid()

If you only want dotted lines at x = 0 & y = 0 use

grid(2,2)

instead.

thanks for the reply..

i tried the code below.. it shows the graph.. but how do i make x and y
axis
show up in the middle??

i am teaching secondary school math.. and i need to produce graphs for
learning purpose..

i need nice x- y-axis.. in the middle.. with arrows at the end of axis..

can you tell me how i can realize that??

The easiest way is to just use ?curve (type ?curve at the prompt to
get documentation for curve): e.g., curve(x^3, from = -5, to = 5)

You could also build the plot yourself like:

x <- seq(-5, 5, length.out = 200)
y <- x^3

plot(x,y)

can anybody tell me how i can draw x- y- axis and draw x^3 graph using
R graph??

i need nice coordinate system with legends and coordinate
numberings..

and nice graph of x^3 on it.. ?it will be nice if you tell me how i
can center the graph..

i want the origin (0,0) to be right in the middle of the graph.

thank you so much.
