Information Visualization (8) - R 그래픽 기초 (선 그리기Adding Connected Line Segments)

기본형태

lines(x, y, lty=str, lwd=num, col=str)

1. lty=int or name

선의 스타일 (기본값 "solid")

"blank", "solid", "dashed", "dotted", "dotdash", "longdash", "twodash" 등이 있으며 아래 샘플 참조.

> plot.new()

> plot.window(xlim = c(0, 10), ylim = c(0, 10))

> axis(1)

> axis(2)

> lines(c(0,10),c(1,1),lty="solid")

> lines(c(0,10),c(2,2),lty="dashed")

> lines(c(0,10),c(3,3),lty="dotted")

> lines(c(0,10),c(4,4),lty="dotdash")

> lines(c(0,10),c(5,5),lty="longdash")

> lines(c(0,10),c(6,6),lty="twodash")

> box()

> box()

2. lwd=num

라인의 폭 결정(기본값은 1)

> plot.new()

> plot.window(xlim = c(0, 10), ylim = c(0, 10))

> axis(1)

> axis(2)

> lines(c(0,10),c(1,1),lty="solid", lwd=0.5)

> lines(c(0,10),c(2,2),lty="solid", lwd=1)

> lines(c(0,10),c(3,3),lty="solid", lwd=2)

> lines(c(0,10),c(4,4),lty="solid", lwd=3)

> box()

> 

3. lend=int or name

라인의 끝 모양 결정(기본값은 "round")

"round", "butt", "square" 의 세종류가 있음

> plot.new()

> plot.window(xlim = c(0, 10), ylim = c(0, 10))

> axis(1)

> axis(2)

> lines(c(0,10),c(1,1),lty="solid", lwd=5, lend="square")

> lines(c(0,10),c(2,2),lty="solid", lwd=5, lend="round")

> lines(c(0,10),c(3,3),lty="solid", lwd=5, lend="butt")

> box()

> 

4. ljoin=int or name

라인의 결합 스타일 (기본값은 "round")

> plot(c(0, 0, 4, 0, 0), c(0, 1, 1.5, 2, 3), type="l", lwd=5, ljoin="round")

> plot(c(0, 0, 4, 0, 0), c(0, 1, 1.5, 2, 3), type="l", lwd=5, ljoin="mitre")

> plot(c(0, 0, 4, 0, 0), c(0, 1, 1.5, 2, 3), type="l", lwd=5, ljoin="bevel")
