NA正被绘制在boxplot ggplot2中 [英] NA's are being plotted in boxplot ggplot2

问题描述

我试图在ggplot2中绘制一个v。简单的boxplot。我有物种丰富与土地利用类。但是，我的数据中有2个NA。出于某种奇怪的原因，即使他们被R理解为NA，他们也会被绘制出来。任何建议将其删除？

我使用的代码是：

  ggplot（data ，aes（x = luse，y = rich））+ 
 geom_boxplot（mapping = NULL，data = NULL，stat =boxplot，position =dodge，outlier.colour =red，outlier.shape = 16，outlier.size = 2，notch = F，notchwidth = 0.5）+ 
 scale_x_discrete（luse，drop = T）+ 
 geom_smooth（method =loess，aes（group = 1 ））
  

但是，该图包含2个用于luse的NA。不幸的是我不能发布图片，但想象一下NA图吧被添加到我的图中。 您可以尝试使用 subset（）函数在您的代码的第一行

  ggplot data = subset（data，！is.na（luse）），aes（x = luse，y = rich））+ 
  

建议如下：从ggplot中消除新生

I'm trying to plot a v. simple boxplot in ggplot2. I have species richness vs. landuse class. However, I have 2 NA's in my data. For some strange reason, they're being plotted, even when they're being understood as NA's by R. Any suggestion to remove them?

The code I'm using is:

ggplot(data, aes(x=luse, y=rich))+
  geom_boxplot(mapping = NULL, data = NULL, stat = "boxplot", position = "dodge", outlier.colour = "red", outlier.shape = 16, outlier.size = 2, notch = F, notchwidth = 0.5)+
  scale_x_discrete("luse", drop=T)+
  geom_smooth(method="loess",aes(group=1))

However, the graph includes 2 NA's for luse. Unfortunately I cannot post images, but imagine that a NA bar is being added to my graph.

解决方案

You may try to use the subset() function in the first line of your code

ggplot(data=subset(data, !is.na(luse)), aes(x=luse, y=rich))+
