R：ggplot：错误：未知参数：binwidth，bin，pad

问题描述

我想用ggplot2做一个非常简单的直方图。我有以下MWE：

 库（ggplot2）
 mydf<  -  data.frame（
基因= c（APC，FAT4，XIRP2，TP53，CSMD3，BAI3，LRRK2，MACF1，
TRIO，SETD2 ，APF，ERBB4，FBXW7，NF1，PDE4DIP，
PTPRT，SPEN，ATM，FAT1，SDK1，SMG1 GLI3，HIF1A，ROS1，
BRDT，CDH11，CNTRL，EP400，FN1，GNAS，LAMA1，PIK3CA $ bPOLE，PRDM16，ROCK2，TRRAP，BRCA2，DCLK1，EVC2，LIFR，
MAST4，NAV3 b Freq = c（48,39,35,28,26,17,17,17,16,15,14,14,14,14,14,14,14,13，
 13,13 ，13,12,12,12,11,11,11,11,11,11,11,11,11,11,11,10,10,10，
 10,10,10）） 
 mydf 
 ggplot（mydf，aes（x = Gene））+ 
 geom_histogram（aes（y = Freq），
 stat =identity，
 binwidth = .5，alpha = .5，
 position =identity）
  

我有总是使用这个简单的代码来生成这种直方图。

事实上，我有一段时间以前提到的这个特例的情节...

但是，现在我运行这个完全相同的代码，我收到以下错误：

为什么我现在发现这个错误，而不是之前，这是什么意思？

非常感谢！ >

解决方案

我宁愿使用 dplyr （管道操作符）来清楚地了解代码：

  mydf％>％#my data frame 
 as.data.frame％>％#if mydf不是数据帧
 ggplot（aes（x = Var，y = n））
 + geom_bar（aes（y = n），stat =id实体，position =identity）
  

I want to do a very simple histogram with ggplot2. I have the following MWE:

library(ggplot2)
mydf <- data.frame(
                  Gene=c("APC","FAT4","XIRP2","TP53","CSMD3","BAI3","LRRK2","MACF1",
                  "TRIO","SETD2","AKAP9","CENPF","ERBB4","FBXW7","NF1","PDE4DIP",
                  "PTPRT","SPEN","ATM","FAT1","SDK1","SMG1","GLI3","HIF1A","ROS1",
                  "BRDT","CDH11","CNTRL","EP400","FN1","GNAS","LAMA1","PIK3CA",
                  "POLE","PRDM16","ROCK2","TRRAP","BRCA2","DCLK1","EVC2","LIFR",
                  "MAST4","NAV3"),
                  Freq=c(48,39,35,28,26,17,17,17,16,15,14,14,14,14,14,14,14,14,13,
                  13,13,13,12,12,12,11,11,11,11,11,11,11,11,11,11,11,11,10,10,10,
                  10,10,10))
mydf
ggplot(mydf, aes(x=Gene)) +
      geom_histogram(aes(y=Freq),
      stat="identity",
      binwidth=.5, alpha=.5,
      position="identity")

I have always used this simple code to produce this kind of histograms.

In fact, I have the plot for this particular example that I made some time ago...

However, now I run this exact same code, and I get the following error:

Why do I find this error now and not before, and what does it mean?

Thanks a lot!

解决方案

I rather would use dplyr (pipe operator) for clear understanding of the code:

   mydf %>%  #my data frame
     as.data.frame %>%  #if mydf is not a dataframe
     ggplot(aes(x = Var, y = n))
       + geom_bar( aes(y = n), stat = "identity", position = "identity")
