我有以下元组s12.tbl和ref.tbl。

s12.tbl <- structure(list(Sample_name = c("s1", "s2", "s1", "s2", "s1",

使用此代码在s12.tbl中为s1创建一个ECDF图表没有问题：

library(dplyr)
library(ggplot)

# Here we only pick S1, 
s1.tbl <- s12.tbl %>% filter(Sample_name=="s1")
s1.tbl <- s1.tbl %>% 
       mutate(some_score=some_score %>% as.numeric)

ref.tbl <- ref.tbl %>% 
       mutate(some_score=some_score %>% as.numeric) %>% 
       setNames(c("Sample_name", "some_score","category"))

dat <- rbind(s1.tbl, ref.tbl)


ggplot(dat, aes(x = some_score)) +
    stat_ecdf(aes(group = Sample_name, colour = category, alpha=category)) +
    scale_alpha_discrete(range = c(0.5, 1)) +
    scale_color_manual(values = c("black","red")) +
    theme_minimal(base_size=15) +
    theme(legend.title=element_blank()) +
    theme(axis.text.x=element_text(angle=45, hjust=1,size=15)) +
    theme(axis.text.y=element_text( hjust=1,size=10)) +
    ylab("ECDF")  +
    xlab("Score")

产生这个：
