TITLE(lines @@ Add Connected Line Segments to a Plot)
USAGE(
lines(x, y, DOTS)
lines.default(x, y=NULL, type="l", col=par("col"), DOTS)
)
ALIAS(lines)
ALIAS(lines.default)
ARGUMENTS(
ARG(x, y @@ coordinate vectors of points to join.)
ARG(type @@ characer indicating the type of plotting; actually any of
the LANG(type)s as in LANG(LINK(plot)(..)).) 
ARG(col @@ color to use. )
ARG(DOTS @@ Further graphical parameters (see LANG(LINK(par))) may
also be supplied as arguments, e.g., LANG(lty).)
)
DESCRIPTION(
LANG(lines) is a generic function taking the coordinates given in the LANG(x)
and LANG(y) vectors and joining the corresponding points with line segments.
The coordinates can alternatively be passed to LANG(lines)
in a plotting structure (a list with x and y components),
a time series, etc.
)
SEEALSO(
LANG(LINK(points)), LANG(LINK(plot)).

EXAMPLES(
data(cars)
# draw a smooth line through a scatter plot
plot(cars, main="Stopping Distance versus Speed")
lines(lowess(cars))
