R seq_len（n）中出错：参数必须可强制为非负整数

只是在R非常新-我错过了什么？ 我觉得这和团体有关？以及as.因子（名称）

谢谢你指出错误和文件，这样我可以阅读和学习

克里斯

您有少于两个数据点的组，这些数据点将被删除。结果是

max

返回

-Inf

。试着不要刻面，看看会发生什么。哦，我想要刻面，但我明白你的意思-让我看看是否有办法不丢失数据点

library("ggplot")

test <- tibble(
  name = c("TEAMA", "TEAMA", "TEAMA", "TEAMB", "TEAMB"),
  percent = c(22.4, 18.8, 43.5, 25.5, 13.8),
  eff = c(.36, .62, .43, .16, .08),
  groups = factor(c("f","f","b","f","b"), levels = c("f","b")),
  col = c(1,2,1,1,1)
)
ggplot(data=test, aes(x=percent, y=eff, color=as.factor(name))) +
  facet_grid(groups ~ col) +  
  stat_density_2d()
