Drawing simple graphs

The simplest graph will be a straight line. For R, we have the following example:

x<-seq(-3,3,by=0.05) 
y<-2+2.5*x 
plot(x,y,type="b") 

In this simple program, type would specify the format of the line, and b would specify both the spot and the line. The corresponding graph is shown here:

The possible values for type are given in the following table:

Value	Description
p	for points
l	for lines
b	for both
c	for the lines part, alone of b
o	for both overplotted
h	for histogram-like (or high-density) vertical lines
s	for stair steps
S	for other steps (see the following details) ...
