Hi,
I already answered that question in the students forum.  Anyway, shortly
Plot[r[t0,x],{x,x0,x}] will give you the basic 2D plot. t0 is a constat of
your choice (must be a number)
to generate a table of data points of your solution use (note the similarity
wit plot)
Table[r[t0,{x,x0,x1,dx}]
browse the help for table and plot functions
