1. 지난 시간에 그린 g3에 theme.kr을 적용하고, x-축과 y-축의 라벨 수정.
(g4 <- g3 + theme.kr +
xlab("연령") + ylab("생존률(%)"))
2. 전체 제목 추가
(g4 <- g3 + theme.kr +
xlab("연령") + ylab("생존률(%)") +
ggtitle("Graunt 시대와 1993년 미국의 생존함수 비교"))
3. 범례 제목 한글로 수정.
(g4 <- g3 + theme.kr +
xlab("연령") + ylab("생존률(%)") +
ggtitle("Graunt 시대와 1993년 미국의 생존함수 비교") +
labs(colour = "시기"))
4. 범례의 항목 한글로 수정.
(g4 <- g3 + theme.kr +
xlab("연령") + ylab("생존률(%)") +
ggtitle("Graunt 시대와 1993년 미국의 생존함수 비교") +
labs(colour="시기") +
scale_colour_discrete(labels = c("Graunt 시대", "1993년 미국")))
(g5 <- g4 + theme(legend.position = c(0.8, 0.5)))
(g6 <- g5 + scale_x_continuous(breaks = graunt$x) + scale_y_continuous(breaks = graunt$lx.17th))
polygon
으로 그린 최종 작품에 한글 정보 입력.

2. 앞과 같은 방법으로 타이틀과 범례에 한글 입력.
(p5 <- p4 + theme.kr +
xlab("연령") + ylab("생존률(%)") +
ggtitle("Graunt 시대와 1993년 미국의 기대수명 차이"))
3. "Graunt 시대", "1993년 미국", "기대수명의 차이"를 각각 필요한 위치 삽입.
(p6 <- p5 + annotate("text", x = c(20, 40, 70), y = c(20, 60, 90), label=c("Graunt 시대", "기대수명의 차이", "1993년 미국"), family="HCR Dotum LVT"))
4. x-축의 눈금과 y-축의 눈금을 낯익은 값들로 조정.
