我正在使用生存包生成兩個羣體的KM曲線,但是當我嘗試定義xmax參數時,我無法擴展x軸範圍從0-15 0 - 50.R:生存包中的KM曲線圖更改x軸範圍
這是我的代碼:
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"))
這是形式真正的窮人,包括'RM(名單= LS())'在你的例子代碼 - 一個天真的SO用戶可以在會話其中運行他們也在工作。 – mnel
另外,我們應該如何訪問您的CSV文件? – mnel
