在ggsurvplot中更改标签名称

Question

我已在下面附上我的数据。

我希望重新标记“累积事件数”，这似乎是默认文本。我想读它：“累积的重复次数”。我似乎无法弄清楚如何改变它 - 甚至可以改变文本？

我的图表看起来像这样：

用这个计算图表

library(survival)
library(survminer)
library(ggplot2)
fit <- survfit(Surv(p$time.recur.months, p$recurrence) ~ p$simpson.grade, conf.type="log", data=p)


j <- ggsurvplot(
fit,                     
data = p, 
fun="cumhaz",
risk.table = TRUE,       
pval = TRUE,      
pval.coord = c(0, 0.25),
conf.int = F,         
legend.labs=c("Simpson Grade 1" ,"Simpson Grade 2", "Simpson Grade 3", 
"Simpson Grade 4"),
 size=c(0.7,0.7,0.7,0.7),                    
 xlim = c(0,100),
 alpha=c(0.7),
 break.time.by = 10,    
 xlab="Time in months",
 #ylab="Survival probability",
 ggtheme = theme_gray(),             
 risk.table.y.text.col = T,
 risk.table.y.text = TRUE,           
 ylim=c(0,0.5),
cumevents=T,
 palette="Set1"       
)

Answer 1

要更改cumevents表的标题，您需要使用参数cumevents.title。

ggsurvplot(fit, p, 
           fun = "cumhaz",
           risk.table = TRUE, cumevents = TRUE,
           pval = TRUE, pval.coord = c(0, 0.25), conf.int = FALSE,
           legend.labs = paste("Simpson Grade", 1:4),
           xlab = "Time in months",
           cumevents.title = "Cumulative number of recurrences",
           size = rep(0.7, 4),
           xlim = c(0, 100), ylim = c(0, 0.5),
           alpha = 0.7,
           break.time.by = 10,
           ggtheme = theme_gray(),
           risk.table.y.text.col = TRUE,
           risk.table.y.text = TRUE,
           palette = "Set1")
