Now, we plot the same three lines but
this time differentiate them by line
thickness using the
clwidth()
(connect
line width) option.

We could create a similar graph using
the
clwidth()
option and specify the
widths as relative sizes, making the line
four times as wide for the
line
plot,
two times as wide for the
lfit
command, and half as wide for the line
for the
lowess
command.

Margins
We can specify the size of a margin in three different ways. We can use a word that rep-
resents a predefined margin. These include
zero
,
vtiny
,
tiny
,
vsmall
,
small
,
medsmall
,
medium
,
medlarge
,
large
,and
vlarge
. They also include
top bottom
to indicate a medium
margin at the top and bottom, and
sides
to indicate a medium margin at the left and right.
A second method is to give four numbers giving the margins at the left, right, top, and bot-
tom. A third method is to use expressions such as
b=5
to modify one or more of the margins.
These are illustrated below. See [
