我正在尝试使用 R 创建分组条形图.我尝试了以下代码来创建一个简单的条形图.
x=c(99,9,104,67,86,53,83,29,127,31,179,86,74,80,100,150,68,18,81,47)名称(x)= c(A",C",E",D",G",F",I",H",K",M",L","N","Q","P","S","R","T","W","V","Y")条形图(x)y= c(105673,18140,92426,76776,93974,53470,75155,30700,77847,28863,124602,55703,50160,60685,78693,69581,70846,18285,92789,45728)名称(y)= c(A",C",E",D",G",F",I",H",K",M",L","N","Q","P","S","R","T","W","V","Y")条形图(y)我必须结合上面两个条形图.我不知道如何组合它们.
我尝试使用 gplot.
require(ggplot2)数据(我的数据)头(我的数据)ggplot(mydata, aes(aminoacid, fill=cut)) + geom_bar(position="dodge") +选择(标题=氨基酸分析")数据帧错误(x = c(2L, 3L, 5L, 4L, 7L, 6L, 9L, 8L, 10L, 12L, 11L, :参数意味着不同的行数:21、228我也尝试了以下代码.
counts <- table(mydata)barplot(counts, main="氨基酸分析",`xlab="氨基酸代码", col=c("darkblue","red")`legend = rownames(counts), beside=TRUE))barplot.default(counts, main = "氨基酸分析", 中的错误:高度"必须是向量或矩阵我该如何解决这些错误?
请帮我用 R 创建一个分组的条形图.
解决方案欢迎来到 SO.
您可能想查看 ggplot2 ,在
# 分组条形图计数 <- 表(mtcars$vs,mtcars$gear)barplot(counts, main="Gears 和 VS 的汽车分布",xlab="齿轮数", col=c("darkblue","red"),图例 = 行名(计数),旁边 = TRUE)
I am trying to create grouped bar plot with R. I tried the following code to create a simple barplot.
x=c(99,9,104,67,86,53,83,29,127,31,179,86,74,80,100,150,68,18,81,47) names(x)= c("A","C","E","D","G","F","I","H","K","M","L","N","Q","P","S","R","T","W","V","Y") barplot(x) y= c(105673,18140,92426,76776,93974,53470,75155,30700,77847,28863,124602,55703, 50160,60685,78693,69581,70846,18285,92789,45728) names(y)= c("A","C","E","D","G","F","I","H","K","M","L","N","Q","P","S","R","T","W","V","Y") barplot(y)I have to combine the above two bar plots. I can't figure out how to combine them.
I tried with gplot.
require(ggplot2) data(mydata) head(mydata) ggplot(mydata, aes(aminoacid, fill=cut)) + geom_bar(position="dodge") + opts(title="aminoacid analysis ") Error in data.frame(x = c(2L, 3L, 5L, 4L, 7L, 6L, 9L, 8L, 10L, 12L, 11L, : arguments imply differing number of rows: 21, 228I tried the following code also.
counts <- table(mydata) barplot(counts, main="amino acid analysis",`xlab="aminoacid codes", col=c("darkblue","red")`legend = rownames(counts), beside=TRUE)) Error in barplot.default(counts, main = "aminoacid analysis", : 'height' must be a vector or a matrixHow can I solve these errors?
Please help me to create a grouped barplot with R.
解决方案Welcome to SO.
You might want to look at ggplot2 , on Hadley's page you will find detailed examples how to do it. Here's an example:
# if you haven't installed ggplot, if yes leave this line out install.packages("ggplot2") # choose your favorite mirror require(ggplot2) data(diamonds) # check the dataset head(diamonds) # plot it ggplot(diamonds, aes(clarity, fill=cut)) + geom_bar(position="dodge") + opts(title="Examplary Grouped Barplot")What's nice about the ggplot2 package is that you can change the visualization of some parameter (aesthetic,aes) easily. For example you could look into facects or stacked barcharts instead of grouping them. Plus, it's well documented on Hadley's page.
For the sake of completeness, here's also a non ggplot2 example found @quickR
# Grouped Bar Plot counts <- table(mtcars$vs, mtcars$gear) barplot(counts, main="Car Distribution by Gears and VS", xlab="Number of Gears", col=c("darkblue","red"), legend = rownames(counts), beside=TRUE)
