这是我的例子
library(survival)
fit <- survfit(Surv(time, status) ~ sex, data = lung)
plot(fit, col=c("orange","purple"), lty=c(1:2), lwd=3, # base with some customization
conf.int = TRUE, xmax = 2000)
# add a legend
legend(100, .2, c("Ovarian Cancer", "Breast Cancer"),
lty = c(1:2), col=c("orange","purple"))
这是情节的样子:
我也试过了
legend('bottomleft', c("Ovarian Cancer", "Breast Cancer"),
lty = c(1:2), col=c("orange","purple"))
传说只看起来略胜一筹
有人知道如何修复传奇吗?
Update 我在Win 7上,R是3.3.3
