警告消息的含义：删除了包含缺失值的4行（geom_path） [英] The meaning of Warning message: Removed 4 rows containing missing values (geom_path)

问题描述

数据： https://drive.google.com/file/ d / 0B20HmmYd0lsFSmZhYUk3bkRTNFk / edit？usp = sharing

plot.df<- read.table("meansses.txt")

theme_luke <- function (base_size = 12, base_family = "") {
theme_gray(base_size = base_size, base_family = base_family) %+replace% 
theme(
  panel.background = element_rect(fill="white"),
  panel.grid.minor.y = element_blank(),
  legend.key = element_rect(fill="white", colour= "white"),
  strip.background = element_rect(fill="white")
)   
}
theme_set(theme_luke())

ggplot(plot.df, aes(factor(L2),mean)) + 
 geom_point(stat = "identity",aes(shape=L3), size=4, group=L3) +
 scale_shape(solid = FALSE) +
 geom_errorbar(aes(ymax = mean + se, ymin = mean - se)) +
 facet_grid(. ~ L1) +
 xlab("Levels") + ylab("Proportion") +
 ylim(0,0.12)

除了当我设置 ylim 我得到

Warning message:
Removed 4 rows containing missing values (geom_path) .

有人可以向我解释这种情况下的含义吗？

Can somebody explain to me what that means in this context?

推荐答案

警告意味着某些元素因为超出指定范围而被删除。在你的情况下，所有点都在范围内，但是一个错误栏不是。

The warning means that some elements are removed because they fall out of the specified range. In your case, all points are inside the range, but one error bar is not.
