我正在使用生存包生成两个群体的KM曲线,但是当我尝试定义xmax参数时,我无法扩展x轴范围从0-15 0 - 50.R:生存包中的KM曲线图更改x轴范围
这是我的代码:
library(sm)
library(survival)
comb = read.csv("S:/Novocure/ChemoSKTime2Resp.csv", head = TRUE)
comb
survobj = with(comb, Surv(SK.response.time,Censored))
survobj
# Compare the survival distributions of nonresponders(0) and responders(1)
fitresp = survfit(survobj ~ response, data=comb)
fitresp
summary(fitresp)
# plot the survival distributions by response
plot(fitresp, xlab="Tumor Progression Time in Months",
ylab="% Progressed", yscale=100, col=c("red","blue"),
main="Chemo Time to Tumor Progression Distribution", xmax = 50)
legend("topright", title="Chi-sq = 5.2, P = 0.0222",
c("Non-responders", "Responders"), fill=c("red", "blue"))
这是形式真正的穷人,包括'RM(名单= LS())'在你的例子代码 - 一个天真的SO用户可以在会话其中运行他们也在工作。 – mnel
另外,我们应该如何访问您的CSV文件? – mnel
